Question

Out of 2-Bromobutane, 1-Bromobutane, 2-Bromopropane and 1-Bromopropane, the molecule which is chiral in nature is:

• A. 2-Bromobutane
• B. 1-Bromobutane
• C. 2-Bromopropane
• D. 1-Bromopropane

Hint:

Look for a carbon that is bonded to four different groups in order to identify chiral centers in molecules.

Answer 1

The Correct Option is A

A molecule is chiral if a carbon atom is attached to four distinct substituents, resulting in a mirror image that cannot be superimposed (enantiomers). 2-Bromobutane is chiral; its central carbon (C2) is bonded to a methyl group, a hydrogen atom, a bromine atom, and an ethyl group, which are four different substituents. The remaining molecules lack a chiral center.
