1) Why does polysubstitution frequently occur with Friedel-Crafts alkylation but not with Friedel-Crafts acylation?2) If Benzene is reacted with t-butyl chloride, why is the chief disubstituted product the para rather than ortho isomer?

Answers

Answer:

See explanation

Explanation:

Friedel-Crafts alkylation frequently undergo polysubstitution because the process  leads to the addition of an electron donating alkyl group, which activates the benzene ring to further alkylation. The acyl group rather deactivates the ring towards electrophilic substitution.

When benzene is reacted with t-butyl chloride, the chief disubstituted product is the para rather than ortho isomer because the increased bulk of the tert-butyl group hinders attack at the ortho-sites.

Calculate the equilibrium concentration of H3O in the solution if the initial concentration of C6H5COOH is 0.056 M . Express your answer using two significant figures.

Answers

Answer:

1.9 × 10⁻³ M

Explanation:

Step 1: Write the acid ionization of benzoic acid

C₆H₅COOH(aq) + H₂O(l) ⇄ C₆H₅COO⁻(aq) + H₃O⁺(aq)

Step 2: Calculate the acid ionization constant (Ka) of benzoic acid

The pKa of benzoic acid is 4.20

pKa = -log Ka

Ka = antilog -pKa = antilog -4.20 = 6.31 × 10⁻⁵

Step 3: Calculate the equilibrium concentration of the hydronium ion

Considering that the initial concentration of the benzoic acid is Ca = 0.056 M, we can calculate the equilibrium concentration of the hydronium ion using the following expression.

[H₃O⁺] = √(Ca × Ka) = √(0.056 × 6.31 × 10⁻⁵) = 1.9 × 10⁻³ M

Answers

Answer:

the answer

Explanation:

the answer

The pH of the solution can be calculated using the Ka value and molarity of the acid. pH of the acid is obtained as 2.26.

What is pH?

pH of a solution is the measure of acidity or basicity. Mathematically it is the negative logarithm of H+ ion concentration in the solution.

pH = - log [H+]

The constant Ka is called ionization constant of an acid. Acetic acid ionizes into equimolar concentrations of H+ and CH₃COO- ions. The Ka can be written as:

[tex]\rm K_{a} = \frac{[CH_{3}COO^{-}][H+]}{[CH_{3}COOH]}[/tex]

Where, [CH₃COO-] = [H+] Thus the expression becomes changed and from the values of Ka and molarity of the acid, H+ ion concentration can be calculated.

6.5 × 10⁻⁵ = [H+]² / [0.461 M]

 [H+] = 0.0054.

Now, the pH can be calculated as follows:

pH = - log [0.0054]

     =  2.26.

Therefore, the pH of the acidic solution is 2.26.

2. Why would a calcium (Ca) atom be larger than a bromine (Br) atom even
though they both have 4 energy levels? *

Answers

Within a period, the atom size decreases with increasing group number (from left to right), since the nuclear charge and the number of external electrons increase within the period, but the number of shells does not. The electrons are more strongly attracted to the nucleus and are therefore closer to the nucleus.

C. Mg and Ca
D. S and Ar

Answers

Answer:

C. mg and Ca

Explanation:

These chemical elements are collectively called as the Alkaline Earth Metals. Calcium and Magnesium are two of the six elements that fall into this category. The outer electronic structure of all these elements is similar due to which they all have similarity in their chemical and physical properties. They are all shiny, though fairly soft but still harder than alkali metals. Further, these are usually white or silvery coloured elements.They react with water to form hydrogen gas and metal hydroxide and with oxygen, they form oxides.

The heat of vaporization for benzaldehyde is 48.8 kJ/mol, and its normal boiling point is 451.0 K. Use this information to determine benzaldehyde’s vapor pressure (in torr) at 53.5°C. Report your answer to three significant digits.

Answers

Answer:

[tex]p_2=5.17torr[/tex]

Explanation:

Hello.

In this case, by using the Clausius-Clapeyron Equation which allows us to relate the vapor pressure, temperature and heat of vaporization as shown below:

[tex]ln(\frac{p_1}{p_2} )=\frac{\Delta _vH}{R}(\frac{1}{T_2}-\frac{1}{T_1} )[/tex]

Whereas [tex]p_1[/tex] is 760 torr due to the normal conditions. In such a way, for computing the vapor pressure of benzaldehyde at 53.5 °C (326.65 K), we proceed as shown below:

[tex]\frac{p_1}{p_2} =exp[\frac{48800J/mol}{8.314\frac{J}{mol*K}}(\frac{1}{326.65K}-\frac{1}{451.0K} )]\\\\\frac{p_1}{p_2}=147.0[/tex]

Thus, the vapor pressure at the final T is:

[tex]p_2=\frac{p_1}{147.0}=\frac{760torr}{147.0}\\ \\p_2=5.17torr[/tex]

Which would have the LEAST gravitational potential energy (GPE)? A ball sitting on the ground An airplane flying 30,000 feet above the ground A rock sitting on top of Mt. Everest​

Answers

Answer:

(A) A ball sitting on the ground

Explanation:

The option with the least gravitational potential energy in the question is : A: A ball sitting on the ground.

Gravitational potential energy can be regarded as the energy  that is been stored in an object due to its vertical position or height.

The energy is stored in the object due to the gravitational attraction of the Earth as regards the object.

To calculate the Gravitational potential energy, we can use

[tex]U= mgh[/tex]

h= height of the object

m= mass of the object.

In The first option, the ball is on the ground, so it has no height or vertical position making it the least object with Gravitational potential energy. Unlike the airplane that is of some miles to the ground.

Therefore, option A is right.

In the reaction between lead(II) nitrate and sodium chloride, what, if any, are the spectator ions

Answers

Answer:

Explanation:

Spectator ions are ions in a solution/reaction that do not take part in a chemical reaction (hence are called "spectator" ions). They can be identified when they are found both in the reactant and product sides.

The reaction between lead(II) nitrate, Pb(NO₃)₂ and sodium chloride, NaCl is illustrated below

Pb(NO₃)₂ + 2NaCl ⇒ PbCl₂ + 2NaNO₃

According to solubility rules, all the compounds above (with the exception of PbCl₂) are all soluble and would dissociate when involved in a reaction.

Hence, the ionic equation based on the description above will be

Pb²⁺ + 2NO₃⁻ + 2Na⁺ + 2Cl⁻  ⇒  PbCl₂ + 2Na⁺ + 2NO₃⁻

From the above ionic equation, it can be noted that both 2NO₃⁻ and 2Na⁺ are found on both the reactant and product side and are hence the spectator ions.

A 500. mL gas sample is collected over water at a pressure of 740 mmHg and 25.0 °C. What is the volume of the dry gas at STP?

Answers

Answer:

Volume of dry gas at STP = 0.432 liters or 432 ml

Explanation:

Given:

Pressure (P) = 740 mmHg - 24 mmHg = 716 mmHg

Temperature (t) = 25 degrees C + 273 K = 298 K

500 ml = 0.5 l

Find:

Volume of dry gas at STP

Computation:

[P1][V1] / T1 = [P2][V2] / T2

[716][0.5] / 298 K = [760][ x Liters] / 273 K

x = 0.432 Liters

Volume of dry gas at STP = 0.432 liters or 432 ml

General Formulas and Concepts:

[tex]Molarity=\frac{moles \hspace{3} of \hspace{3} solute}{liters \hspace{3} of \hspace{3} solution}[/tex]

Explanation:

Step 1: Define variables

0.555 M NaHCO₃

14.7 g NaHCO₃

Step 2: Define conversions

Molar Mass of Na - 22.99 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of C - 12.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of NaHCO₃ - [22.99 + 1.01 + 12.01 + 3(16.00)] g/mol = 84.01 g/mol

1 L = 1000 mL

Step 3: Find moles of solute

[tex]14.7 \hspace{3} g \hspace{3} NaHCO_3(\frac{1 \hspace{3} mol \hspace{3} NaHCO_3}{84.01 \hspace{3} g \hspace{3} NaHCO_3} )[/tex] = 0.174979 mol NaHCO₃
