Molecules whose m A. 2-Bromobutane

B. 1-Bromobutane

C. 2-Bromopropane

D. 2-Bromopropan-2-ol

The structure of 2-Bromobutane is shown below. All the groups attached to the central carbon atom are different, making the mirror image of molecule non superimposable over original molecule.

The structure of 1-Bromobutane is given below. There are only three groups different from each other, hence the molecule is not chiral in nature.

The structure of 1-Bromopropane is given below. Again, there are only three groups different from each other, and the molecule is not chiral.

The structure of 2-Bromopropan-2-ol, given below, again has two similar species and thus cannot be chiral.
