Question

Give valence bond description for the bonding in the complex [vcl4]-. draw box diagram for free metal ion. which hybrid orbitals are used by the metal ? state the no.of unpaired electrons​

Answer 1

Answer:

c)  $v^{+3}$ion has the electronic configuration [ Ar] 3$d^{2}$and the orbital diagram is

given below.

[ VC$l_{4}$] is tetrahedral, the  $v^{+3}$ ion uses s$p^{3}$ hybrid orbital in accepting a share in four pairs of electrons from four $Cl^{-}$ ligands.

It has only two unpaired electron which we can see from the hybridisation given below in the attachment.
