Both ways use a grignard reagent, the difference between both ways is that one use an electrophile ketone with a low molecular mass, and the other has a high molecular mass.

The grignard reagent is commonly used to reduce carbonyle groups to alcohols. In the first step, a complex with the reagent is formed in the carbonile, and in the second step, the oxygen atom is hidrated in acid or basic medium and form the respective alcohol.

For the first way, we will use a high molecular mass ketone. In this case the 2-pentanone reacting with CH₃MgBr as a grignard reagent.

For the second way, we will use a low molecular mass ketone, in this case Acetone, reacting with CH₃CH₂CH₂MgBr. Both of them, will give the same product of 2 methyl-2-pentanol. See picture below for that

Explanation:

Radioactive decay is the set of various processes by which unstable atomic nuclei (nuclides) emit subatomic particles (radiation). Decay is said to occur in the parent nucleus and produces a daughter nucleus. This is a random process, i.e. it is impossible to predict the decay of individual atoms.

How atoms interact with other atoms is largely dependant on the number of electrons on its outermost layer. The electrons on this layer are called valence electrons.

As you might know, atoms have their electrons arranged in layers/shells, starting at k, l m, n etc. Each layer has a maximum number of electrons it can accommodate, with the outermost one being the valence shell. The first layer (k) can accomodate 2 electrons, the second one (l) can accomodate 8, as can the third one (m) etc.

As a rule of thumb, most atoms don't like being alone. These atoms have a valence shell that isn't saturated. This is the case for hydrogen(1), with one free slot in its outter shell.

However, atoms like helium are a bit different. They are inert, and don't need to bond with other atoms. This is because their valence shell is saturated. In this case, helium saturated the k shell with 2 electrons. Helium in this form will not form bonds.

However, hydrogen is still out there looking for buddies. Hydrogen will bind with any other atom with a free electron. Being extremely common, it's likely that said atom will be another hydrogen.

However, another common example would be for 2 hydrogens to bond with one oxygen, forming h2O (oxygen can form 2 bonds)

Conclusion : helium is inert and will not interact with other atoms. Hydrogen is not, and thus needs to bond with other atoms.

This is the balanced reaction equation for the combustion of methane.

Explanation:

The Law of Conservation of Mass basically states that matter can neither be created nor destroyed. As such, we must be able to show this in our chemical reaction equations.

If you look at the equation above, you'll see an arrow that separates the reaction equation into two parts. This represents the direction of the reaction.

To the left of the arrow, we have our reactants.

To the right of the arrow, we have our products.

The quantity of each individual element in the left must equal the quantity of each individual element in the right.

So if you look below, you'll see the unbalanced equation, and I'll try to explain how to balance the reaction.

Our next step is to break these down into individual atoms.

We have:

If you're confused by this, look to see the little number to the bottom right of each element, the subscript, and it tells you how many of each atom are in the molecule. Make sense?

Now we look to the other side of the equation.

Here we see our products are

Again, we break these down into individual atoms again.

Answer:

Which atom is oxidized in the reaction of benzhydrol with bleach?

Explanation:

n this experiment, students will perform a simple oxidation reaction of a secondary

alcohol. Recall that Oxidation Is a Loss of electrons while Reduction Is a Gain of electrons (OIL

RIG). In order to apply this mnemonic, you must know the oxidation states of each atom within

the compound, with particular interest on carbon. Carbon can carry oxidation states ranging

from -4 to +4. A few examples are shown in Figure 1 below. It is also common for carbon to

carry an oxidation state of -3, -1, +1, and +3.

Figure 1. Examples of carbon’s oxidation levels.

You may have noticed that all of the compounds in Figure 1 are neutral and carbon has

zero formal charge in each example. The concept of oxidation state and formal charge are

similar with one important difference in the calculation. Both are calculated by taking the

difference between the valence electrons (from the periodic table) and the number of electrons

belonging to that atom within the molecule. For a given atom, the valence electrons will never

change but the electrons ‘belonging’ the atom in the molecule will vary depending on number of

lone pairs and attachments to more or less electronegative atoms. The important difference in

the calculation of oxidation states and formal charge is based on the following assignment of

bonding electrons (Figure 2). This is how the highlighted carbon in ethanol can have an

oxidation state of -1 but a formal charge of zero.

- Oxidation states assign bonding electrons to the more electronegative atom in a bond,

except when the two atoms are the same and the bonding electrons are split equally.

Answer:

so the reaction would probably would be a chemical reaction

"When benzophenone reduces to diphenylmethanol, leftover products include the CH2OH and NaBH3 species. The energetic CH2OH and NaBH3 quickly bond to give (CH2OH)H3B-Na+. This complex is the main second product of benzophenone reduction."

Reactant Ratios

"In life, four benzophenone molecules react with each BH4 complex. Since four benzophenone molecules each attract a hydrogen atom from the “BH4” hydrogen donor, four “CH2OH”s bond with each boron (B) atom. Realistically, the secondary product is (CH2OH)4B-Na+ and four diphenylmethanol molecules. Focusing on one benzophenone molecule at a time is helpful for explaining and understanding reaction steps."

What is Charge ?

Charge is a basic property of matter that is associated with the presence or absence of electrons. Objects can have positive or negative charge, or they can be neutral, which means they have an equal number of positive and negative charges. In physics, charge is one of the fundamental concepts used to explain the behavior of matter and energy in the universe. The interaction between charges is described by Coulomb's law, which states that the force between two charges is proportional to the product of their charges and inversely proportional to the square of the distance between them.

Answer:

5.88 dL = 0.588 litre

Explanation:

We need to find a conversion from 5.88 dL to liters.

We know that the conversion is as follows :

1 deciliter = 0.1 litre

To find 5.88 dL to liters, we use the unitary method. So,

5.88 dL= (0.1×5.88) litre

5.88 dL = 0.588 litre

So, there are 0.588 liters in 5.88 dL.

it can suddenly increase when more and more people have babies and the infant rate goes up. and how it might affect the ecosystem is the pollution that people give off.

Answer:

Explanation:

Due to less predators in the Savannah/habitat, the population could unexpectedly grow. This will have an impact on the environment because it will give rise to more prey as there will be fewer predators. If too many herbivores are present on one feeding site, competition for food will occur. If there are more plants in an area than normal, it can increase the population of animals that consume the plant. If the population of one animal rises, the population of animals that consume that animal could also rise.

Population growth isn't always good. A population may often grow too big to sustain the climate. Other modifications in limiting variables can cause a population to decline. The population will decrease if a population becomes diseased, and the population of animals that consume the diseased animals will decrease as well. Populations in nature typically balance themselves. Sometimes, they can't always restore a natural balance as man affects populations.

Solvent extraction is the process in which a compound transfers from one solvent to another owing to the difference in solubility or distribution coefficient between these two solvents(Science Direct).

We have to remember that oxalic acid will be extracted better into a solvent in which it is more soluble. From the data given; oxalic acid is more soluble in ethanol than in ether.

This simply means that ethanol is a better solvent for extracting oxalic acid  from water when compared to ether.
