On monochlorination of 2-methyl butane, the total number of chiral compounds is

4

The correct answer is option 2. 4.

Compounds which are non-superimposable on their mirror image are called chiral compounds and the carbon should have all the groups or atoms attached to it differently.

2-Methyl butane is an organic chemical compound that has a chain of four carbon atoms and the second carbon atom has a methyl group attached. Monochlorination means one hydrogen atom from the compound is replaced with one chlorine atom. So, the monochlorination of 2-Methyl butane will produce 4 different products. These are 1-chloro-3-methyl butane, 2-chloro-3-methyl butane, 2-chloro-2-methyl butane, and 1-chloro-2-methyl butane.

1-chloro-3-methyl butane: It doesn’t have any carbon atom which has four different groups hence it is achiral. The structure is given below:

2-chloro-3-methyl butane: It has one carbon atom that has four different groups. Hence this compound is chiral. The structure is given below:

2-chloro-2-methyl butane: It doesn’t have any carbon atom which has four different groups hence it is achiral. The structure is given below:

1-chloro-2-methyl butane: It has one carbon atom that has four different groups. Hence this compound is chiral. The structure is given below:
