ChemistryAlcohols, Phenols and EthersJEE Main

Consider: (I) 1,2-dihydroxybenzene (catechol), (II) 1,3-dihydroxybenzene (resorcinol), (III) 1,4-dihydroxybenzene (hydroquinone), (IV) hydroxybenzene (phenol). The increasing order of boiling points of the above-mentioned alcohols is

Answer: (C)

Solution

Phenol (IV), with only one –OH group, has the weakest intermolecular hydrogen-bonding network and the lowest boiling point. Catechol (I, ortho-diol) partly engages in intramolecular hydrogen bonding, reducing the extent of intermolecular association
