Vedclass · Answer

(B) The strength of intermolecular $H$-bonding depends on the electronegativity of the atom attached to the hydrogen atom and the polarity of the bond.In $CH_3NH_2$ (methylamine),$CH_3OH$ (methanol),and $C_6H_5OH$ (phenol),$H$-bonding exists.Phenol $(C_6H_5OH)$ exhibits the strongest intermolecular $H$-bonding because the oxygen atom is attached to a phenyl ring,which increases the acidity of the phenolic hydrogen compared to aliphatic alcohols or amines,leading to a higher partial positive charge $(\delta )$ on the hydrogen atom.Therefore,the correct option is $(B)$.
