Question

Which of the following has an asymmetric center?

CHBr₂Cl BHFCl CH₃CHCl₂ CHFBrCl BeHCl

Short answer

We have to find which compound has asymmetric center:

Only CHFBrCl has asymmetric center.

Step-by-step solution

Definition of asymmetric and stereocenters

What is asymmetric center or chiral carbon-

Chiral objects are those objects which have no same mirror images. The mirror images don’t superimpose each other. whose mirror images superimpose each other that compounds are called achiral objects.

Chiral carbon is that carbon atom which is bonded to four different groups.

What is stereocenters-

An atom with three or more different attachments and interchanging of two of these attachments leads to another stereoisomer that C-center is called as stereocenter.

All asymmetric centers are stereocenters but all stereocenters can’t be asymmetric.

Final answer

CHBr₂Cl = This compound has two Br atoms so it is not chiral carbon so there is no asymmetric center.

BHFCl= No chiral atom so there is no asymmetric center.

CH₃CHCl₂= This compound has two Cl atoms so it is not chiral carbon so there is no asymmetric center.

CHFBrCl= In this all the groups attached to carbon are different so it is asymmetric center.

BeHCl= No chiral atom so there is no asymmetric center.
