Step 2

The number of hydrogen atoms present at the carbon undergoing substitution in each of the product formed in the chlorination of isopentane are as follows:

 

1 hydrogen atoms in 2-chloro-2-methylbutane

2 hydrogen atoms in 2-chloro-3-methylbutane

6 hydrogen atoms in 1-chloro-2-methyl butane

3 hydrogen atoms in 1-chloro-3-methylbutane

 

The percentage of each of the product formed in terms of substitution of one hydrogen is calculated by dividing the percentage of product formed by the number of hydrogen atoms present at substituted carbon atom as shown below.
