The molecular geometry of BCl3 is trigonal planar with symmetric charge distribution around the central atom.
The shape will be tetrahedral with a bond angle of 109.5°. Phosphorus has 5 electrons in its bonding level. According to VSEPR theory the molecule PH3 has a trigonal pyramidal shape due lone pair-bond pair repulsion.
