Question

For the same alkyl group, the boiling point of alkyl halides decrease in the order:

• A. RI> RBr> RCl> RF
• B. RI< RCl< RBr <RF
• C. RI<RBr<RCl<RF
• D. RF<RBr<RCl<RI

Answer 1

The correct option is A

RI> RBr> RCl> RF

The boiling points of alkyl halides decrease in the order RI> RBr> RCl> RF. This is because as the size of halogen increases, the magnitude of van der Waals forces increase, and hence the boiling point increase.
