Given below are two statements : one is labelled as Assertion (A) : and the other is labelled as Reason (R). Assertion (A) : Both rhombic and monoclinic sulphur exist as S_8 while oxygen exists as O_2.
Reason (R) : Oxygen forms pπ - π multiple bonds with itself and other elements having small size and high electronegativity like C,N, which is not possible for sulphur.
In the light of the above statements, choose the most appropriate answer from the options given below :
Select the correct option:
A
Both (A) and (R) are correct and (R) is the correct explanation of (A).
B
Both (A) and (R) are correct but (R) is not the correct explanation of (A).
C
(A) is correct but (R) is not correct.
D
(A) is not correct but (R) is correct.
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
Oxygen can form $2 \mathrm{p} \pi-2 \mathrm{p} \pi$ multiple bond with itself due to its small size while sulphur cannot form multiple bond with itself as $3 p \pi-3 p \pi$ bond will be unstable due to large size of sulphur, but sulphur can form multiple bond with small size atom like C and N .
