Carbon atom in the carbonyl group is: (a) sp - hybridised (b) sp2 - hybridised (c) sp3 - hybridised (d) dsp2 – hybridised

Answer»

Correct Answer is: (b) sp2 - hybridised

In both aldehydes and ketones, the geometry around the carbon atom in the carbonyl group is trigonal planar; the carbon atom exhibits sp2 hybridization. 

Two of the sp2 orbitals on the carbon atom in the carbonyl group are used to form σ bonds to the other carbon or hydrogen atoms in a molecule.
