Question

The total number of six membered cyclic structural as well as stereoisomers possible for compounds with the molecular formula C₈H₁₆ (consider only ethylcyclohexane and the dimethylcyclohexanes) is:

(a) structure (b) (c) (d) (e)

(f) structure (g) (h) (i) (j)

TestHub · Accepted Answer

Ethylcyclohexane (1) + 1,1-dimethylcyclohexane (1) + 1,2-dimethylcyclohexane (3: cis is meso; trans is a pair of enantiomers) + 1,3-dimethylcyclohexane (3: cis is meso; trans is a pair of enantiomers) + 1,4-dimethylcyclohexane (2: cis and trans, both achiral - C₁ and C₄ are not stereocentres) = 1 + 1 + 3 + 3 + 2 = 10.

Ans. 10
