Given below are two statements:
Assertion (A): | Among the two O-H bonds in H2O molecule, the energy required to break the first O-H bond and the other O-H bond is the same. |
Reason (R): | The electronic environment around oxygen is the same even after the breakage of one O-H bond. |
1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |

4. | Both (A) and (R) are False. |
Given below are two statements:
Assertion (A): | Though the central atom of both NH3 and H2O molecules are sp3 hybridised, 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. |
