C = O and C = C bonds are differentiated by:
Correct answer: C. Bond length
- A. Hybridization of C-atom
- B. Planar structures
- C. Bond length
- D. Undergo addition reaction
Explanation
Unlike a C=C double bond, the C=O bond has a dipole. The electrons in the sigma and pi bonds are more attracted to the O than the C. This is because oxygen is much more electronegative than carbon.the C = C bond length is 1.34A.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
