Question

The carbonyl carbon atom:

Options

• All of these

• forms three sigma (σ) bonds

• forms a π-bond with oxygen

• sp²-hybridised

Answer 1

All of these

Explanation:

R₁R₂C=O is carbonyl so 3 sigma bond two sigma bonds with C chain attached (R₁ and R₂) and one sigma bond with the oxygen atom. and it also forms 1 π-bond with oxygen.

The hybridisation of carbonyl carbon = sp² as it forms a total 3 sigma bond and has zero lone pair.

If the number of sigma bond + lone pair = 3 then hybridisation is sp².
