WebApr 8, 2024 · The bond angle observed in ammonia is 107 ∘ and the bond angle of phosphine is 93.5 ∘ . Therefore, the bond angle of P H 3 is much less than N H 3 . Hence, the correct answer is option A. Note: Phosphine is a colourless, flammable and toxic gas having a rotten fish-like smell. Ammonia is a colourless gas with a pungent smell. WebWhy bond angle of NH 3 is greater bond angle of PH 3? Medium Solution Verified by Toppr Nitrogen is more electro-negative than phosphorous and hence attracts electron more towards itself from bond pair with hydrogen, as compared to attraction of electrons by phosphorous in PH 3.
