Vedclass · Answer

(B) In the group $15$ hydrides $(NH_3, PH_3, AsH_3, SbH_3)$, the central atom size increases down the group $(N As the size of the central atom increases, the bond pair-bond pair repulsion decreases, and the electronegativity of the central atom decreases.This leads to a decrease in the bond angle as we move down the group.Therefore, the correct order of bond angles is $SbH_3 < AsH_3 < PH_3 < NH_3$.

The correct order of the bond angles of the given compounds is
