The melting and boiling point of alcohols are high as compared to corresponding alkanes due to
Correct answer: B. Hydrogen bonding
- A. Dipole-dipole interaction
- B. Hydrogen bonding
- C. Ionic interactions
- D. Van der Waal interactions
Explanation
Hydrogen bonding is a specific type of attractive interaction that occurs between a hydrogen atom covalently bonded to a highly electronegative atom and another electronegative atom. This interaction is crucial in many chemical and biological processes. Thus due to presence of -OH they can form hydrogen bonding and this ability is highly significant in lower alcohols compared to higher alcohols and thus alcohols have high melting and boiling points compared to corresponding alkanes

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
