MCQ (Single Correct Answer)

AIPMT 2001

A compound of molecular formula C7H16 shows optical isomerism, compound will be
A
2, 3-dimethylpentane
B
2, 2-dimethylbutane
C
2-methylhexane
D
none of these

Explanation

Organic compounds exhibit the property of enantiomerism (optical isomerism) only when their molecules are chiral. Most chiral compounds have a chiral centre, which is an atom bonded to four different atoms or groups.
2,3-Dimethylpentane has one chiral C-atom and do not have any symmetric element.
