Question

Assertion : The S-S-S bond angle in $S_8$ molecule is ${105}^o$.
Reason : $S_8$ has V-shape.

• A. If both assertion and reason are true and the reason is a correct explanation of the assertion
• B. If both assertion and reason are true but reason is not a correct explanation of the assertion
• C. If the assertion is true but reason is false
• D. If both the assertion and reason are false
• E. If the assertion is false but the reason is true

Answer 1

Answer: (C)

If the assertion is true but reason is false

Sulphur atoms in $S_8$ molecule are $s{p}^3$ hybridised and contain two lone pair of electrons on each sulphur. Thus the S-S-S bond angle will be less than ${109}^o$. However, the $S_8$ molecules exist as staggered eight atom rings.
