STANDARD Chemistry Strength of Acids Assertion Reason Question
Type: Assertion Reason-conceptual-Medium
Statement I : Acid strength increases in the order given as HF << HCl << HBr << HI. Statement II : As the size of the elements F, Cl, Br, I increases down the group, the bond strength of HF, HCl, HBr, and HI decreases and so the acid strength increases. In the light of the above statements, choose the correct answer from the options given below.
A
Statement I is incorrect but statement II is true.
B
Both statement I and statement II are true.
C
Both statement I and statement II are false.
D
Statement I is correct but statement II is false.
Correct Answer
Option B
Detailed Explanation
Both statements are true. Acid strength increases down the group due to decreasing bond strength, making it easier for the hydrogen ion to dissociate.
