Question

In the process : XH₃ + H⁺ → XH₄⁺ , (X being N, P, As
and Sb), the maximum increase in the bond angle will be in
case of
(a) NH₃ (b) PH₃
(c) AsH₃ (d) SbH₃

Answer 1

In the process of XH₃ + H⁺ → XH₄⁺  (X = N, P, As, Sb) the maximum increase in bond angle will be 109.5°,109.5°, 91.3° and 107° respectively.

Explanation:

In the process of NH₃ + H⁺ → NH₄⁺ the maximum increase in bond angle will be 109.5°.

In case of PH₃ + H⁺ → PH₄⁺ the maximum increase in bond angle will be 109.5° while in PH₃ the bond angle is less than 109.5°.

In case of SbH₃ + H⁺ → SbH₄⁺ the maximum increase in bond angle will be 91.3°

In case of AsH₃ + H⁺ → AsH₄⁺ the maximum increase in bond angle will be 107°.
