Question
Assertion: Both rhombic and monoclinic sulphur exist as S8 but oxygen exists as O2.
Reason: Oxygen forms pπ – pπ multiple bonds due to small size and small bond length but pπ – pπ bonding is not possible in sulphur.
Options
Both assertion and reason are correct statements, and reason is the correct explanation of the assertion.
Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion.
Assertion is correct, but reason is wrong statement.
Assertion is wrong but reason is correct statement.
Both assertion and reason are wrong statements.
Solution
Both assertion and reason are correct statements, and reason is the correct explanation of the assertion.
Explanation:
The rhombic and the monoclinic forms of sulphur exist as S8. Oxygen forms a pπ – pπ multiple bond due to its small size and short bond length, but pπ – pπ bonding is not possible because of sulphur's larger atomic size.
