Discuss the concept of hybridisation. What are its different types in a carbon atom.

उत्तर
Different types of hybridization in a carbon atom are:
(a) sp hybridization: The carbon atoms forming triple bonds with each other determine sp hybridized carbon. \[\ce{(C = C)}\].
(b) sp3 hybridization: The carbon atoms forming double bonds with each other determine sp2 hybridized carbon. \[\ce{(C = C)}\].
(c) sp3 hybridization: The carbon atoms forming single bonds with each other determine sp3 hybridized carbon. \[\ce{(C = C)}\].
