What is the hybridization of the carbon atom in an Aldehyde group?

Explanation

Option A: The functional group in aldehydes is a -CHO group. The C atom in the -CHO group forms one pi bond with the O atom. Hence the hybridization of carbon will be sp2.Option B:sp3 hybridization occurs when carbon atom makes single bond with four other atoms.Option C: sp hybridization is observed when one s and one p orbital in the same main shell of an atom mix to form two new equivalent orbitals. The new orbitals formed are called sp hybridized orbitals. It forms linear molecules with an angle of 180°Option D: dsp2 type of hybridization is seen specially in case of transition metal ions. The orbitals involved in this type of Hybridization are dx2- y2, s and two p. If the compound undergoes reaction with strong ligand than dsp2, dsp3,d2sp3 hybridization occurs
