Question

Explain the differences in boiling point of a five carbon alkene, alkyl bromide, and alcohol. What intermolecular forces are involved in holding the molecules in the liquid form?

Answer 1

boiling points order :

alcohol > alkyl halide > alkene

explanation:

1) in alkenes there are only weak dispersion forces are present . so these boiling points are very less

2) compared to alkenes in alkly halide there is increasing in molar mass . molar mass increases the extension of intermolecular forces are increases. so boiling point of alkens are more than alkyl halide

3) in alcohols there are hydrogen bonds are present . hydrogen bonds are strong intermolecular forces compared to alkyl haildes and alkenes. so alcohols having highest boiling point compare two above two
