Answer & Solution

Correct Answer

(B) SbH3<AsH3<PH3<NH3

Step-by-step Solution

Detailed explanation

Among the given compounds, N has the smallest central atom in size and is the most electronegative atom. Due to this, NH3 is the smallest of the given hydrides and gives rise to the largest bond angle. The order of atomic radius of central atom in the given hydrides is,…
