The structure of ammonia $(NH_3)$ is.......

Trigonal bipyramidal geometry is shown by

Explain the non-linear shape of $H_2S$ and the non-planar shape of $PCl_3$ using the Valence Shell Electron Pair Repulsion $(VSEPR)$ theory.

In a regular octahedral molecule,$MX_6$,the number of $X-M-X$ bonds at $180^{\circ}$ is

Based on the $VSEPR$ model,match the xenon compounds given in List-$I$ with the corresponding geometries and the number of lone pairs on xenon given in List-$II$ and choose the correct option.

List-$I$	List-$II$
$(P)$ $XeF_2$	$(5)$ Trigonal bipyramidal and three lone pairs of electrons
$(Q)$ $XeF_4$	$(3)$ Square planar and two lone pairs of electrons
$(R)$ $XeO_3$	$(2)$ Pyramidal and one lone pair of electrons
$(S)$ $XeO_3F_2$	$(4)$ Trigonal bipyramidal and no lone pairs of electrons
