Question

What would be the correct option:
<> Type of Carbon atoms present in CH3CH=CHCN

1)SP3
2) SP2
3) SP3,SP2
4) SP3,SP2,SP

Answer 1

Between last carbon and hydrogen Sp3hydbridisation and b/w CH=CH Sp2hyb and B/WCarbon and nitrogen triple bond Sp hybridisation

Answer 2

In CH3CH=CH2-CN
first carbon is sp3 hybridised (it contains 4 σ bonds)
Second and third carbon are sp2 hybridised (3 σ  bonds and 1 π bond)
Fourth carbon is sp ​hybridised ( it conains 2​σ bonds and 2 π bonds)

so the correct option is 4) Sp3,SP2,SP
