$PH_4^+$

Vedclass · Answer

(B) The bond angle in $PH_4^+$ is larger than in $PH_3$.In $PH_4^+$,the phosphorus atom is $sp^3$ hybridized with a tetrahedral geometry,resulting in a bond angle of approximately $109.5^{\circ}$.In $PH_3$,the phosphorus atom is also $sp^3$ hybridized,but it contains one lone pair of electrons. According to $VSEPR$ theory,the lone pair-bond pair repulsion is greater than bond pair-bond pair repulsion,which compresses the bond angle to approximately $93.6^{\circ}$.

Which has a larger bond angle between $PH_3$ and $PH_4^+$? Why?
