JEE Main Chemistry question

Statement 1 (Assertion): Among chalcogens, tendency of catenation is maximum for sulphur. Statement 2 (Reason): S–S bond dissociation energy is higher than O–O bond dissociation energy.

(A)Assertion is True, Reason is True; Reason is correct explanation for AssertionCorrect
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (A)

Solution

Catenation strength tracks the strength of the element–element single bond; the bond is weakened by strong lone-pair repulsions between the small oxygen atoms, whereas the bond, between larger sulphur atoms, is
