4.21 partc

For this question, the shape is tetrahedral, yet the bond angles are not 109.5 but 103 degrees. It said this had something to do with the double bond between phosphorous and oxygen. Can someone please explain this further to me. Thanks!

Hi Husnia,
Right! The double bonds are the reason for smaller bond angles (103 degrees). The P-O bond needs more space so it causes the P-CL bonds to move closer together to reach 103 degrees.
