Chemistry - CHEMICAL BONDING Question with Solution | TestHub

The correct order of bond angle is${\mathrm{H}}_3\mathrm{T}{\mathrm{e}}^{+}<{\mathrm{H}}_3\mathrm{S}{\mathrm{e}}^{+}<{\mathrm{H}}_3{\mathrm{S}}^{+}<{\mathrm{H}}_3{\mathrm{O}}^{+}$
while the rest orders are incorrect and their correct order is as follows
$\mathrm{N}{\mathrm{H}}_3>\mathrm{P}{\mathrm{H}}_3>\mathrm{A}\mathrm{s}{\mathrm{H}}_3>\mathrm{S}\mathrm{b}{\mathrm{H}}_3$
$\mathrm{O}{\mathrm{F}}_2<\mathrm{O}{\mathrm{H}}_2<\mathrm{O}\mathrm{C}{\mathrm{l}}_2$
$\mathrm{B}{\mathrm{F}}_3=\mathrm{B}\mathrm{C}{\mathrm{l}}_3=\mathrm{B}\mathrm{B}{\mathrm{r}}_3=\mathrm{B}{\mathrm{I}}_3$
