Question

The P–P angle in \( \mathrm{P_4} \) molecule and S–S–S angle in \( \mathrm{S_8} \) molecule (in degree) respectively are:

• A. \(60^\circ, 107^\circ\)
• B. \(107^\circ, 60^\circ\)
• C. \(40^\circ, 60^\circ\)
• D. \(60^\circ, 40^\circ\)

Hint:

Ring strain reduces bond angles significantly.

Answer 1

The Correct Option is A

Step 1: \( \mathrm{P_4} \) is tetrahedral, giving bond angle \(60^\circ\).
Step 2: \( \mathrm{S_8} \) has puckered ring structure with bond angle \(\approx 107^\circ\).
