The H–O–H bond angle in H_2O is 104.5° and not 109°28' because of

JEE Main Chemistry question

The H–O–H bond angle in is 104.5° and not 109°28' because of

(A)High electronegativity of oxygen
(B)Bond pair-bond pair repulsion
(C)Lone pair-lone pair repulsionCorrect
(D)Lone pair-bond pair repulsion

Answer: (C)

Solution

Oxygen in water has 2 lone pairs in addition to its 2 bond pairs. Lone pair-lone pair repulsion is the strongest type of electron-domain repulsion (stronger than lone pair-bond pair or bond pair-bond pair repulsion), and
