The H \(-N-H\) angle in ammonia is \(107.6^{\circ}\) while the \(\mathrm{H}-\mathrm{P} -\mathrm{H}\) angle in phosphine is \(93.5^{\circ} .\) Relative to phosphine, the \(p\) -character of the lone-pair on ammonia is expected to be
- A Less
- B More
- C Same
- D Cannot be predicted
Answer & Solution
Correct Answer
(A) Less
Step-by-step Solution
Detailed explanation
Key point As the percentage of s character in a bond increases, the bond angle also increases. Therefore. as the bond angle increases, the percentage of \(p\) -character decreases. In the given options, Ammonia ( \(\mathrm{NH}_{3}\) ) has bond angle \(=107.6^{\circ}\) and…
