Given below are two statements:
Assertion (A): | Sodium chloride, formed by the action of chlorine gas on sodium metal, is a stable compound. |
Reason (R): | Sodium and chloride ions acquire octets in sodium chloride formation. |
1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
3. | (A) is True but (R) is False. |
4. | (A) is False but (R) is True. |
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. |
1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |

4. | (A) is False but (R) is True. |
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). |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
