Q.

Match List-I with List-II.

Choose the correct answer from the options given below:

  1. A

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

  2. B

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

  3. C

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

  4. D

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

Solution

(A) 2-methylpropene vs but-1-ene differ in carbon skeleton → chain isomers (III).
(B) cis/trans-but-2-ene → stereoisomers (I).
(C) 2-butanol vs diethyl ether share the same molecular formula but different functional groups → functional isomers (IV).
(D) but-1-ene vs but-2-ene differ only in the position of the C=C → positional isomers (II).
