Answers

Answer 1

Catalytic hydrogenation is classified as a 1,2-addition reaction. in this experiment, hydrogen was added to the alkene of 1-decene in a syn (cis) fashion.

a) Syn: A process by which all new bonds are formed on one face of the reactant molecule during an addition reaction.

b) the role of platinum metal (pt) in this syn addition reaction is to be a catalyst and be a hydrogen quencher.

An addition reaction in organic chemistry is an organic process whereby two or more molecules come together to form a larger one (the adduct). Because they also have double-bond nature, molecules containing carbon—hetero double bonds, such as carbonyl (C=O) or imine (C=N) groups, can be added.

According to Arrhenius definition a compound is an acid when, in aqueous solution it can releases protons. and  a compound is a base when, in aqueous solutions it can releases hydroxides anions.

According to Arrhenius, the acids are the hydrogen-containing compounds which give H+ ions or protons on dissociation in water and bases are the hydroxide compounds which give OH− ions on dissociation in water.

Arrhenius theory is only applicable only in the aqueous solution, for example, according to the Arrhenius theory, HCl is an acid in the aqueous solution but not in benzene, even though it donates H +  ion to the benzene. Also, under Arrhenius’s definition, the solution of sodium amide in liquid ammonia is not alkaline, even though amide ion deprotonates the ammonia.

So, for the acidic and basic properties, the presence of water is necessary.

This theory does not explain acidic and basic character of substances in non-aqueous solvents.

In case of HClO4 when it is subjected to dissociation it produces hydronium ion in the solution and hence it can be termed as an acid.

malonyl-coa is an intermediate in fatty acid synthesis. it also regulates fatty acid metabolism. which of the molecules regulate the enzyme that catalyzes malonyl‑coa synthesis?

Answers

Malonyl CoA regulates a variety of enzymes, including fatty acid synthase, acetyl-CoA carboxylase, and carnitine palmitoyltransferase I.

Malonyl CoA is an important regulatory molecule that is involved in the control of fatty acid synthesis. It is the precursor molecule to acetyl CoA and is produced in the cytosol of cells from acetyl CoA by the enzyme acetyl-CoA carboxylase. Malonyl CoA then serves as a substrate for a variety of enzymes, which are regulated by their levels.

One of the enzymes that Malonyl CoA regulates is fatty acid synthase (FAS). FAS catalyzes the conversion of acetyl CoA and malonyl CoA into long-chain fatty acids. The enzyme is activated when Malonyl CoA binds to the active site, which induces a conformational change in the enzyme that increases the affinity of the enzyme for its substrate.

Another enzyme that Malonyl CoA regulates is acetyl-CoA carboxylase (ACC). ACC catalyzes the carboxylation of acetyl CoA to form malonyl CoA. This enzyme is regulated by Malonyl CoA, as the presence of Malonyl CoA in the active site of the enzyme inhibits its activity. This serves to prevent the production of excessive amounts of Malonyl CoA, which could otherwise lead to excessive fatty acid synthesis.

Finally, Malonyl CoA also regulates the enzyme carnitine palmitoyltransferase I (CPT-I). CPT-I is responsible for the transport of long-chain fatty acids across the mitochondrial membrane, a process that is necessary for the oxidation of fatty acids. Malonyl CoA binds to CPT-I, inhibiting its activity and thus preventing fatty acid oxidation. This serves to maintain the levels of Malonyl CoA in the cytosol, ensuring that it can be used for fatty acid synthesis.

Answers

The sample contains number of moles of gas is 0.39 mol. The mass of the helium is 1.56 g.

Given,

Volume of the gas = 30L

Pressure = 2.1atm

Temperature = 298K

R = 0.0821 L.atm/(mol.K)

To find:

Number of moles = ?

Mass of helium = ?

Solution:

To find the mass of helium in the container, use the expression below:

Mass of helium  = number of moles x molar mass

Using the ideal gas equation;

PV = nRT

Where,

P is the pressure

V is the volume

n is the number of mole

R is the gas constant

T is the temperature

Substitute the values and solve for n;

2.1 x 30  = n x 0.0821 x 298

⇒ n = 24.4658 / 63

⇒ n = 0.39

Now,

molar mass of He = 4g/mol

For instance, water cannot dissolve hydroxides, fats, or waxes because oppositely charged particles are not very soluble in water.

Explain how you determined the polarity of all your compounds by first predicting the polarity of water, and then mixing different solutes and solvents to find the polarities of the other substances.

Answers

Likes disintegrate. Nonpolar materials dissolve in nonpolar substance, while polar materials dissolve in polar solvents. like vinegar and water. Because they're both polar molecules, they were polar.

n alternating copolymer is known to have a number-average molecular weight of 250,000 g/mol and a degree of polymerization of 3420. if one of the repeat units is styrene, which of ethylene, propylene, tetrafluoroethylene, and vinyl chloride is the other repeat unit? why?

Answers

Chain fraction is styrene and unknown repeat units in an alternating copolymer, followed by each type of repeat unit. If the other is Styrene, a repeat unit of an alternating copolymer forms.

With the chemical formula C6H5CH=CH2, styrene is an organic substance. Although older samples may appear yellowish, this benzene derivative is an oily, white liquid. Although large concentrations have a less savoury flavour , the chemical readily evaporates and has a sweet smell of styrene. A copolymer is a polymer produced from more than one type of monomer in polymer science. Copolymerization is the process by which monomers are polymerized into copolymers. Bipolymers are the name given to copolymers created through the copolymerization of two monomer types. The formula for m is as follows: m = Mn / Dp m = 250000 / 3420 = 73.09g/mol.
