NEET 2021 Chemistry Bond Strength and Acid Strength Relationship Assertion Reason Question
Type: Assertion Reason-conceptual-Medium-Class 12
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
Both Statement I and Statement II are true.
B
Both Statement I and Statement II are false.
C
Statement I is correct but Statement II is false.
D
Statement I is incorrect but Statement II is true.
Correct Answer
Option A
Detailed Explanation
Both statements are true. Acid strength increases down the group as bond strength decreases, making it easier for the acid to dissociate.
