Question

in (NC) ² C=C (CN) ² hybrid state of C is​

Answer 1

The hybrid state of Carbon in (NC)2-C=C-(CN)2 is sp2 as well as sp.

In the organic compound (NC)2-C=C-(CN)2, the carbon attached to the Nitrogen with a triple bond is sp hybridized, and the carbon attached to another carbon with a double bond is sp2 hybridized.

Now the question arises that why is the hybridization of two types of carbon in a single compound different from each other?

The answer is simple. It is because of the number of π bonds to which the carbon is bonded.

Hence, we can conclude that calculating the number of π bonds is the easiest way by which we can determine the hybridization of an element in a compound.

For example,

                    0 π bond = sp3 hybridization

                    1 π bond = sp2 hybridization

                    2 π bond = sp hybridization
