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–C; III–B; IV–A

Solution

Acetamide and benzonitrile are essentially neutral in water, triethylamine is basic, and phenol is weakly acidic. Thus I-C, II-C, III-B, IV-A.
