Does sf4 showa back bonding?

Expert Answer:

There are two types of bonds are present in the SF4 that are Axial bonds and equatorial bonds.
SF4 has four bonded atoms and one lone pair. The five electron pairs around sulphur adopt trigonal bipyramidal geometry in which one position is occupied by a lone pair. This lone pair finds a position that minimizes the number of 90o repulsions it has with bonding electron pairs. It occupies an equatorial position with two 90o repulsions. The bonded electrons occupy the axial and equatorial positions. The axial S-F bonds are bent slightly away from the lone pair. Hence, all the bonds in SF4 are not equivalent.
hence there is no backbonding in SF4.
