  • Assertion (A) : Though the central atom of both NH3 and H2O molecules are sp3 hybridized, yet H–N–H bond angle is greater than that of H–O–H. Reason (R) : This is because nitrogen atom has one lone pair and oxygen atom has two lone pairs.

In the following questions, a statement of Assertion (A) followed by a statement of the reason (R) is given. Choose the correct option out of the choices given below each question.

Assertion (A) : Though the central atom of both NH3 and H2O molecules are sp3 hybridized, yet H–N–H bond angle is greater than that of H–O–H.
Reason (R) : This is because nitrogen atom has one lone pair and oxygen atom has two lone pairs.
