Question

Which of the following haloalkanes is most reactive?

• A. 1-chloropropane
• B. 1-bromopropane
• C. 2-chloropropane
• D. 2-bromopropane

Answer 1

The correct option is A 1-chloropropane

Among chlorine and bromine chlorine is more reactive as it is better leaving group than bromine.

On the other hand, which has the open side, it is the open side. In the given option 1-chloro has the open side so it is more reactive than 2-chloro.

So, option A is the correct answer.
