The number of chiral centres in a molecule 5-bromo 3-chloro hexan-2-ol is/are:
- A
1
- B
3
- C
2
- D
5
A chiral centre is an atom especially in an organic molecule that has four unique atoms or groups attached to it. To 3 carbons three different functional groups are attached. Therefore, 3 chiral centers are present.
Note. To other adjacent carbon don't confuse the fact that 2 H are attached irrespective of different functional groups so they can’t be considered chiral.
If there is only one chiral center in the molecule, it means there is only one carbon atom with four different substituents attached to it. A chiral center is also known as a stereocenter, and its presence indicates that the molecule is chiral and can have enantiomers (mirror-image isomers).

If there are two chiral centers in the molecule, it means there are two carbon atoms, each with four different substituents attached.
If there are five chiral centers in the molecule, it means there are five carbon atoms, each with four different substituents attached.
