In aqueous solution, identify the nature of each compound in List I and match it with List II. List I I. Acetamide II. Benzonitrile III. Triethylamine IV. Phenol List II A. Acidic B. Basic C. Neutral

1. I–C; II–C; III–B; IV–A
2. I–B; II–C; III–C; IV–A
3. I–C; II–B; III–A; IV–C
4. I–A; II–A; III–C; IV–B

Correct answer: I–C; II–B; III–A; IV–C

Solution

Acetamide is neutral due to its amide group, benzonitrile is basic because it can accept protons due to the presence of the nitrile group, triethylamine is basic as it has a lone pair of electrons on nitrogen that can accept protons, and phenol is acidic due to the ability of its hydroxyl group to donate a proton.
