Intermolecular hydrogen bonding is strongest in

Options

A. Methylamine
B. Phenol
C. Formaldehyde
D. Methanol

Answer

D

Explanation

Methanol has - OH group due to which there will be more intermolecular hydrogen bonding among the given molecules.
`...H-oversetunderset(|)(CH_3)O....H-oversetunderset(|)(CH_3)O....H....oversetunderset(|)(CH_3)O`
We know that which the increases of electronegativity and decrease in size of the atom to which hydrogen is covalently linked, the strength of the hydrogen bond increases.
