Question

Free radical chlorination of hexane produces this number of monochloroderivatives (including stereoisomers)?

• A. $5$
• B. $7$
• C. $8$
• D. $3$

Answer 1

Answer: (A)

$5$

For hexane, we have :

8 secondary hydrogens and

6 primary hydrogens

We will get 1-chloro hexane, 2-chloro hexane and 3-chloro hexane. 3 different hydrogens are replaced with a chlorine atom to get 3 different monochlorination products.

In 2-chloro hexane and 3-chloro hexane, they each form a racemic mixture. So a total of 5 isomers are formed after monochlorination of hexane.

Hence the correct option is A.
