Question

what is the state of hybridisation of carbon in CO₃2- and graphite?

Answer 1

Hybridization of Carbon in;
CO₃^2- = >
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
