Answer & Solution
Correct Answer
(C) (B) only
Step-by-step Solution
Detailed explanation
(A) True, carboxylic acids form extensive hydrogen bonds, leading to higher boiling points than aldehydes and ketones. (C) True, carboxylic acids (as salts) undergo decarboxylation when heated with soda lime to produce alkanes. (D) True, carboxylic acids are acidic enough to…
