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.
