**Assertion:** Among chalcogens, the tendency towards catenation is maximum for sulphur. **Reason:** The S-S bond dissociation energy is higher than the O-O bond dissociation energy.

JEE Main Chemistry question

**Assertion:** Among chalcogens, the tendency towards catenation is maximum for sulphur. **Reason:** The - bond dissociation energy is higher than the - 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

Sulphur shows the greatest catenation tendency among the chalcogens, forming extensive chains and rings (Assertion true). This is because the larger sulfur atoms experience much less lone-pair–lone-pair repulsion
