Question

Explain hybridisation of carbonate

Answer 1

The carbonate ion, CO3 2- is has a trigonal planer geometry meaning the carbon is sp2 hybridized. ... Carbonateanion on the basis of the three-electron bond.

Answer 2

Hybridization of Carbon in;
CO32- = > 
Total valance electron = 4 (carbon) + 3 x 6(for oxygen) = 22
Total available electrons = 22 + 2 (ionic charge) = 24
Bond pair = 3
Electrons involved in octet formation = 8 x3 = 24
Hence, lone pair = 0
Hybridization = sp2 
In graphite; hybridization of carbon is also = ​ sp2
