Assertion (A): | The relative strength of acids can be determined by knowing the value of the dissociation constant. |
Reason (R): | It provides the value of [H+] dissolved in the solution. |
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) and (R) both are false |
Given below are two statements:
Assertion (A): | The increasing order or acidity of hydrogen halides is HF<HCI<HBr<HI. |
Reason (R): | While comparing acids formed by the elements belonging to the same group of the periodic table, H-A bond strength is a more important factor in determining the acidity of an acid than the polar nature of the 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). |
3. | (A) is True but (R) is False. |
4. | (A) is False but (R) is True. |
Assertion: acts as both Bronsted Lowry base as well as Lewis base.
Reason: It acts as both acceptor and a lone pair donor.
