State the hybridization and draw the structures of $PCl_3$ and $PCl_5$.

(N/A) For $PCl_3$: The central phosphorus atom is $sp^3$ hybridized. It has $3$ bond pairs and $1$ lone pair,resulting in a trigonal pyramidal geometry.
For $PCl_5$: The central phosphorus atom is $sp^3d$ hybridized. It has $5$ bond pairs and $0$ lone pairs,resulting in a trigonal bipyramidal geometry.
