PCl5 has a trigonal bipyramidal geometry. In this geometry, there are two types of P-Cl bonds:
Therefore, the statement "All five P - Cl bonds are identical in length" is incorrect. The other statements are correct: PCl5 has two different bond angles (90° and 120°), exhibits sp3d hybridization, and consists of five sigma bonds.
