Match List I with List II. List I (Pairs of compounds) List II (Types of isomerism) A. Ethoxyethane and 1-Methoxypropane I. Chain isomerism B. Pentan-1-ol and 3-Methylbutan-1-ol II. Position isomerism C. Butanal and Butan-2-one III. Functional isomerism D. Butan-1-amine and Butan-2-amine IV. Metamerism Choose the correct answer from the options given below:

Options

  1. AA-IV, B-I, C-III, D-II
  2. BA-IV, B-II, C-III, D-I
  3. CA-II, B-I, C-III, D-IV
  4. DA-III, B-I, C-IV, D-II

Correct answer

A. A-IV, B-I, C-III, D-II

Step-by-step solution

Let us analyze each pair of compounds: A. Ethoxyethane ( CH ₃ CH ₂- O - CH ₂ CH ₃ ) and 1-Methoxypropane ( CH ₃- O - CH ₂ CH ₂ CH ₃ ) have the same molecular formula ( C ₄ H ₁₀ O ) and the same polyvalent functional group (ether) but differ in the alkyl groups attached to the oxygen atom. This is an example of metamerism. (A IV) B. Pentan-1-ol and 3-Methylbutan-1-ol have the same molecular formula ( C ₅ H ₁₂ O ) and the same functional group ( - OH ) at the same position, but they differ in the length of the princi
