how can we say carbonyl compounds have substantial dipole moment than ether?

Dear Student,

In the carbonyl compounds, the carbonyl group contains a double bond between carbon and oxygen atom- one σ and one π bond whereas C-O bond in ethers consists of a single covalent ​σ bond, The ​π  electrons are loosely held in C=O which can be readily shifted to carbonyl oxygen due to the high electronegativity of oxygen. Consequently, the magnitude of +ve and -ve charge developed in carbonyl (C=O) bond is higher than C-O bond of ethers.Hence, carbonyl compounds have higher dipole moment than corresponding ethers.
