Solution:

In the carbonyl group, carbon atom is in a state of hybridisation. One hybrid orbital overlap with a unhydridised -orbital of oxygen to form -bonds. The remaining two orbitals of carbon form -bonds with -orbitals of hydrogen or -orbitals of carbon of the alkyl groups. The -bond is formed by the sideways overlap of -orbitals of carbon and oxygen. Thus, the three -bonds of carbonyl carbon lie in one plane and are aprat
