Which of the following is the correct statement for hybridization of C-atom and number of \(\sigma\) and \(\pi\) bonds in the Carbonyl group?
- A \(\text{Sp}^2, 3\sigma, 1\pi\)
- B \(\text{Sp}, 3\sigma, 1\pi\)
- C \(\text{Sp}^3, 3\sigma, 1\pi\)
- D \(\text{Sp}^3, 2\sigma, 2\pi\)
Answer & Solution
Correct Answer
(A) \(\text{Sp}^2, 3\sigma, 1\pi\)
Step-by-step Solution
Detailed explanation
Carbonyl carbon has 3 electron domains (1 double bond, 2 single bonds). Hybridization: \(\text{sp}^2\). \(\sigma\) bonds for carbonyl carbon: \(1\) (in \(\text{C=O}\)) + \(2\) (to R groups) = \(3\sigma\). \(\pi\) bonds for carbonyl carbon: \(1\) (in \(\text{C=O}\)) = \(1\pi\).
