Inoic bonds are usually formed by combination of elements with
high ionisation potential and low electron affinity
low ionisation potential and high electron affinity
high ionisation potential and high electron affinity
low ionisation potential and low electron affinity
If a molecule MX3 has zero dipole moment, the sigma bonding orbital used by M (At. no. 13) are
pure p
sp- hybridised
sp2- hybridised
sp3- hybridised
C.
sp2- hybridised
If dipole moment of the molecule is zero, this will imply that the molecule is symmetrical or it has no lone pairs of electrons.
Electronic configuration of 13M - 1s2, 2s2, 2p6, 3s2, 3p1
Structure of MX3 is X-MX-X
So, number of molecular hybridisation = 3. Hence,sp2 hybrid orbitals are used.
