Write the structure for each of the following alcohols and label at 1°, 2° or 3°.
(i) 3-Chloro butanol.
(ii) 3, 3-dimethyl cyclopentanol.
(iii) 3-chloro-2-methyl-1-butanol.
The high boiling points of alcohols are mainly due to the presence of intermolecular hydrogen bonding in them which is lacking in ethers and hydrocarbons.
