Question

Give reason for the following:

1. Haloalkanes easily dissolve in organic solvents.
2. n-Butyl bromide has higher B. pt than f-butyl bromide.
3. Vinyl chloride is unreactive in substitution nucleophilic reactions.

Answer 1

1. The intermolecular forces exists between haloalkane is of comparable strength as that of organic solvents and haloalkanes, hence haloalkanes easily get dissolved in organic solvents.
2. n-Butyl bromide has larger surface area as compared to t-butyl bromide, hence there is stronger van der walls attraction among molecules of n-butyl bromide, so it has more boiling point.
3. Due to resonance there is partial double bond character in the bond between C and chlorine, hence substitution nucleophilic reaction is not posible.
