Which from following compounds has lowest boiling point?

Step-by-step solution

The boiling point of alcohols is influenced by hydrogen bonding and London dispersion forces, both present in these compounds. Hydrogen bonding occurs through the hydroxyl group, contributing significantly to boiling points. London dispersion forces increase with molecular size and surface area, strengthening with additional carbon atoms. Methanol ( CH₃ OH ) possesses only one carbon atom, resulting in the weakest London dispersion forces among the alcohols. While hydrogen bonding is present, the reduced molecular
