The correct answer is Option B.
The chiral carbon atom is one in which there are an unequal number of carbon atoms, this happens only in option (B) as it forms a non superimposable mirror image.

Which of the following compound does have chiral carbon atom?a)(CH3)2C...
Explanation:
A chiral carbon atom is a carbon atom that is bonded to four different groups or atoms. This means that the four groups attached to the carbon atom must be different from each other.
Let's analyze each option to determine if it has a chiral carbon atom or not:
Option A: (CH3)2CHCH2CH2Br
In this compound, the carbon atom bonded to the bromine atom has two hydrogen atoms and two methyl groups attached to it. Since two of the groups attached to the carbon atom are the same (hydrogen), it is not a chiral carbon atom.
Option B: CH3CH2CH2CH (Br)CH3
In this compound, the carbon atom bonded to the bromine atom has two hydrogen atoms, one methyl group, and one ethyl group attached to it. All four groups attached to the carbon atom are different, so it is a chiral carbon atom.
Option C: CH3CH2CH(Br) CH2CH3
In this compound, the carbon atom bonded to the bromine atom has two hydrogen atoms, one methyl group, and one ethyl group attached to it. All four groups attached to the carbon atom are different, so it is a chiral carbon atom.
Option D: CH3CH2CH2CH2Br
In this compound, the carbon atom bonded to the bromine atom has three hydrogen atoms and one methyl group attached to it. Since three of the groups attached to the carbon atom are the same (hydrogen), it is not a chiral carbon atom.
Therefore, the correct answer is Option B, CH3CH2CH2CH (Br)CH3, which has a chiral carbon atom.
A chiral carbon atom is a carbon atom that is bonded to four different groups or atoms. This means that the four groups attached to the carbon atom must be different from each other.

Option D: CH3CH2CH2CH2Br
In this compound, the carbon atom bonded to the bromine atom has three hydrogen atoms and one methyl group attached to it. Since three of the groups attached to the carbon atom are the same (hydrogen), it is not a chiral carbon atom.
Therefore, the correct answer is Option B, CH3CH2CH2CH (Br)CH3, which has a chiral carbon atom.
