Question is based on the following passage: Methyl nitrile is hydrolysed to carboxylic acid in the presence of H+ or OH- as catalyst. An intermediate compound [A] is formed during this reaction.
Which of the following is the correct statement for hybridization of C-atom and number of π bonds in the Carbonyl group?
Sp², 3σ, 1π
- In a carbonyl group (C=O), the carbon is sp² hybridized. The sp² hybridization of carbon leads to the formation of one σ-bond with the oxygen atom, and another σ-bond with the other substituent (such as hydrogen or another carbon). The remaining p-orbitals on carbon and oxygen overlap to form a π bond.
- Thus, the carbon in the carbonyl group has 3 σ bonds and 1 π bond.
- The correct answer is (a) Sp², 3σ, 1π.
