Question

How many assymmetric carbon atoms are present in
(i) 1,1-dimethylcyclohexane
(ii) Methylcyclopentane
(iii) Methylcyclohexane

• A. (i)-1, (ii)-0, (iii)-0
• B. (i)-1, (ii)-1, (ii)-1
• C. (i)-0, (ii)-0, (iii)-0
• D. (i)-2, (ii)-1, (iii)-0

Answer 1

The correct option is C (i)-0, (ii)-0, (iii)-0

A asymmetric carbon in an organic compound is a carbon atom directly connected to four different groups.
Number of asymmetric carbon atoms in
1,1-dimethylcyclohexane = 0
Methylcyclopentane = 0
Methylcyclohexane = 0
