Question

The melting and boilong point of haloalkenes is more than parent hydrocarbon why

Answer 1

Haloalkanes generally have a boiling point that is higher than the alkane they are derived from. ... For the same alkyl group, the boiling point of haloalkanes decreases in the order RI > RBr > RCl > RF.This is due to the increase in van der Waals forces when the size and mass of the halogen atom increases.
