O B) 1,1-Chlorocycloalkanes
O C) 1,3-Dichloroalkanes
O D) 1,2-Dichloroalkanes​

Answer 1

Answer:

A) 1-Chlorocycloalkanes

Answer 2

The cycloalkanes react with the chlorine in presence of UV light to give 1- Chlorocycloalkane.

• The reaction is catalyzed by UV light so the reaction will follow a free radical mechanism.
• In this mechanism, there will be the formation of Chlorine-free radical first.
• The chlorine-free radical will then attack the more positive carbon on the cycloalkane.
• But since all the carbon atoms are the same in cycloalkane, there will be the formation of a monosubstituted cycloalkane.
• Therefore, the 1- Chlorocycloalkane formation will occur.
