Unformatted text preview: Cl-Si-Cl if you fill all 3 atoms with full octets, you end up with 20 e’s. So, discard 2 e’s and form another bond between Si and Cl: Cl-Si = Cl Si-Cl bonds are both polar; molecule is polar since the 2 polar bonds don’t cancel out. b) trigonal planar since there are 3 electron domains around Si c) angular or bent d) 120° (or, better still: < 120 ° - i.e. slightly less than 120° ) e) since the electron domain geometry is trigonal planar, the hybridization of Si must be sp 2 ....
