Here are the answers to your questions: xxxix. Write any four derivatives of carboxylic acid (4 marks) The four derivatives of carboxylic acid are: 1. Acid halides (e.g., acyl chlorides, R-COCl) 2. Acid anhydrides (e.g., R-CO-O-CO-R) 3. Esters (e.g., R-COOR') 4. Amides (e.g., R-CONH_2) xl. Briefly comment on the difference in boiling point of alcohol and carboxylic acid (4 marks) Carboxylic acids generally have higher boiling points than alcohols of comparable molecular weight. This is because, in addition to forming hydrogen bonds like alcohols, carboxylic acids can form dimers through two strong hydrogen bonds between two carboxylic acid molecules. This dimerization significantly increases the effective molecular weight and the strength of intermolecular forces, requiring more energy to overcome during boiling. Alcohols, while capable of hydrogen bonding, do not form such stable dimeric structures. Send me the next one 📸
