Question

does bromo alkane have a lower boiling point as compared to fluro and chloro alkanes? or is the order of increasing boiling point RF

Answer 1

For the same alkyl group , Boiling point of alkyl halide decreases in the order -
RI > RBr > RCl > RF
​Thus, bromo alkane has higher boiling point than fluoro alkane and chloro alkane. As the size and mass of halogen increases, vander waal forces of attraction increases, so , Boiling point increases.
