Some Basic Principles Of Organic Chemistry Question 130

Question: Which of the following compounds is not chiral [AIEEE 2004]

Options:

A) 1-chloro-2-methyl pentane

B) 2-chloropentane

C) 1-chloropentane

D) 3-chloro-2-methyl pentane

Show Answer

Answer:

Correct Answer: A

Solution:

To be optically active the compound or structure should possess chiral or a symmetric centre but in the rest of the structures it is present.
