Assertion (A): Increasing order of acidity of hydrogen halides is
HF < HCl < 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
an important factor in determining the acidity of acid than the
polar nature of the bond.
(i) Both A and R are true and R is the correct explanation of A.
(ii) Both A and R are true but R is not the correct explanation of A.
(iii) A is true but R is false.
(iv) Both A and R are false.
Option (i) Both A and R are true and R is the correct explanation of A is correct
