Carboxylic acids are stronger acids than alcohols

A. This is because the carboxy anion is delocalised.
B. This is because the hydrogen atom is delocalised.
C. The O-H bond in carboxylic acids is very strong.
D. This statement is not true

One characteristic of monomers that form addition polymers that is not common in monomers which form condensation polymers is:
A. the presence of alkyl side chains
B. the presence of two functional groups.
C. the presence of pi bonds.
D. None of the above.

For the first question, the correct answer is A. Carboxylic acids are stronger acids than alcohols because the carboxylate anion formed after losing a proton is stabilized by resonance, meaning the negative charge is delocalized over the oxygen atoms in the carboxylate group. This delocalization of the charge increases the stability of the anion, making it easier for the acid to donate a proton.


To answer the second question, the correct answer is B. Monomers that form addition polymers have only one functional group, which allows them to undergo addition polymerization. In contrast, monomers that form condensation polymers typically have two functional groups that can react with each other to eliminate a small molecule (such as water) during polymerization. This stepwise reaction process is characteristic of condensation polymerization.

Therefore, the presence of two functional groups is not common in monomers that form addition polymers, making choice B the correct answer.

The correct answers are:

1. D. This statement is not true. Alcohols are generally weaker acids than carboxylic acids due to the presence of the carboxyl group (-COOH) in carboxylic acids which increases their acidity.

2. B. the presence of two functional groups. Monomers that form addition polymers typically have only one functional group for polymerization, while monomers that form condensation polymers have two functional groups that undergo a condensation reaction to form the polymer.
