Match List I with List II. List I List II A. Propan-1-amine and N-methylethanamine I. Chain isomers B. Butan-1-ol and Butan-2-ol II. Position isomers C. Pentane and 2-Methylbutane III. Functional isomers D. 1-Methoxypropane and Ethoxyethane IV. Metamers Choose the correct answer from the options given below:
Options
- AA-III, B-I, C-II, D-IV
- BA-III, B-II, C-I, D-IV
- CA-IV, B-II, C-I, D-III
- DA-IV, B-I, C-II, D-III
Correct answer
B. A-III, B-II, C-I, D-IV
Step-by-step solution
Let us analyze each pair in List I: A. Propan-1-amine is a primary ( 1^ ) amine, while N-methylethanamine is a secondary ( 2^ ) amine. Primary, secondary, and tertiary amines are considered functional isomers. Thus, A matches with III. B. Butan-1-ol and Butan-2-ol have the same parent carbon chain length (4 carbons) but differ in the position of the principal functional group ( -OH ). They are position isomers. Thus, B matches with II. C. Pentane has a straight chain of 5 carbons, whereas 2-Methylbutane has a paren
