Question

athe type of backbonding present in pf3 molecule is

s p pi-2 p pi
2 pi-3 p pi
3 d pi-2 p pi
2p pi-5 p pi​

Answer 1

Answer:

Back bonding is possible in PF3 as P has vacant d orbital(as its atomic no. is 15 therefor its electronic configuration is 1s(2e) 2s(2e) 2p(6e) 3s(2e) 3p(3e) this shows it has vacant 3d orbital which can perform back bonding with fluorine as fluorine has pair of electrons. Mark me as the
