There are six isomeric alkenes (A, B, C, D, E, and F) that require 1 mol of `H_(2)` per mole of alkene for hydrogenation and give the same product (G) on hydrogenation. G is an alkane having the lowest molecular mass and is optically active. Write the structure of compounds from A to G.

Explanation

First, wire the structure of G. It can be:
(I) or (II)
(I) can be obtained by six different alkene but (II) can be obtained by five different alkenes. So G is (I)
