What is the state of hybridisation of carbon in (a) \mathrm{CO}_{3}{ }^{2-}(\mathrm{b}) diamond (c) graphite?
What is the state of hybridisation of carbon in (a) \mathrm{CO}_{3}{ }^{2-}(\mathrm{b}) diamond (c) graphite?

Solution:

The condition of hybridization of carbon in:
(a) C O_{3}^{2-}
c in \mathrm{CO}_{3}^{2-} is sp ^{2} hybridized and is attached to 3 oxygen iotas.
(b) Diamond
Every precious stone carbon is hybridized by sp 3 and is bound to 4 extra carbon iotas.
(c) Graphite
Every carbon iota in graphite is hybridized with sp 2 and is bound to 3 different molecules of carbon.
