$SbH_3$

Vedclass · Answer

(D) The bond angle in hydrides of group $15$ and $16$ elements decreases down the group due to the decrease in electronegativity of the central atom and the increase in the size of the central atom.For group $15$ hydrides $(NH_3, PH_3, AsH_3, SbH_3)$,the bond angle decreases as: $NH_3 (107^\circ) > PH_3 (93.6^\circ) > AsH_3 (91.8^\circ) > SbH_3 (91.3^\circ)$.For group $16$ hydrides $(H_2O, H_2S, H_2Se, H_2Te)$,the bond angle decreases as: $H_2O (104.5^\circ) > H_2S (92.1^\circ)$.Comparing all given options,$SbH_3$ has the lowest bond angle of approximately $91.3^\circ$ because $Sb$ is the largest and least electronegative atom among the central atoms listed,leading to maximum $p$-orbital character in the bonding and minimum bond angle.
