Vedclass · Answer

(A) For isomeric alkyl halides,the boiling point decreases as the branching increases. This is because branching leads to a decrease in the surface area of the molecule,which in turn reduces the magnitude of the van der Waals forces of attraction. Therefore,the primary $(1^o)$ alkyl halide has the highest surface area and the strongest intermolecular forces,while the tertiary $(3^o)$ alkyl halide has the lowest surface area and the weakest intermolecular forces. The correct order is $1^o > 2^o > 3^o$.

The correct order of melting and boiling points of the primary $(1^o)$,secondary $(2^o)$ and tertiary $(3^o)$ alkyl halides is:
