Comment on the nature of two SтИТObonds formed in SO2┬аmolecule.Are the two SтИТO bonds in this molecule equal?



Answer -

The electronic configuration of Sis 1s2┬а2s2┬а2p6┬а3s2┬а3p4.

During the formation of┬аSO2, one electron from 3p┬аorbitalgoes to the 3d┬аorbital and S undergoes┬аsp2┬аhybridization. Two of these orbitals formsigma bonds with two oxygen atoms and the third contains a lone pair.┬аp-orbital and┬аd-orbitalcontain an unpaired electron each. One of these electrons forms┬аp╧А-┬аp╧А┬аbondwith one oxygen atom and the other forms┬аp╧А-┬аd╧А┬аbond with the other oxygen. This is the reason SO2┬аhas a bent structure. Also, it is aresonance hybrid of structures┬аI┬аand┬аII.

Both SтИТO bonds are equal in length (143 pm) and have amultiple bond character.
