Question

State the hybridisation of 2carbon atoms in CH3-CHO from left to right

Answer 1

From the structure it is clear that C1 is making sigma bonds only, therefore it is sp3 hybridised.C2 is making a double bond therefore it is sp2 hybridised.

C1 is sp3 hybridized and C2 is sp2 hybridized.

Hope its Help you!!
