Vedclass · Answer

(D) $1$. Boiling point of alcohols depends on the surface area of the molecule and the extent of intermolecular hydrogen bonding.$2$. As the branching in the alkyl chain increases, the surface area of the molecule decreases, which reduces the magnitude of van der Waals forces.$3$. Among the given isomers, $n$-Butyl alcohol is a straight chain, while $tert$-Butyl alcohol is highly branched.$4$. Due to maximum branching, $tert$-Butyl alcohol has the smallest surface area and the weakest intermolecular forces, resulting in the lowest boiling point.

Which of the following isomers of $C_4H_9OH$ has the lowest boiling point?
