Bond angle in alcohols is slightly less than the tetrahedral angle because of

Question

Bond angle in alcohols is slightly less than the tetrahedral angle because of (A) electronegativity of oxygen (B) H -bonding (C) repulsion between the unshared electron pairs of oxygen (D) none of these.

Tardigrade Admin · Accepted Answer

The oxygen in alcohols is s p3 hybridised but it has two lone pairs present on it and repulsion in lone pair-lone pair is greater than bond pair-bond pair repulsion. Thus bond angle of alcohols decreases from tetrahedral angle.

Q. Bond angle in alcohols is slightly less than the tetrahedral angle because of

electronegativity of oxygen

$H$ -bonding

repulsion between the unshared electron pairs of oxygen

none of these.

The oxygen in alcohols is $s p^{3}$ hybridised but it has two lone pairs present on it and repulsion in lone pair-lone pair is greater than bond pair-bond pair repulsion. Thus bond angle of alcohols decreases from tetrahedral angle.
