Vedclass · Answer

(A) The boiling point of alcohols depends on the extent of intermolecular hydrogen bonding and the surface area of the molecule. As the branching increases from primary $(1^{\circ})$ to secondary $(2^{\circ})$ to tertiary $(3^{\circ})$ alcohols,the surface area of the molecule decreases. $A$ smaller surface area leads to weaker van der Waals forces of attraction. Additionally,steric hindrance in tertiary alcohols reduces the effectiveness of intermolecular hydrogen bonding. Therefore,the boiling point decreases in the order: $1^{\circ} > 2^{\circ} > 3^{\circ}$.

The correct order of boiling point for primary $(1^{\circ})$,secondary $(2^{\circ})$ and tertiary $(3^{\circ})$ alcohols is
