The Keto form of phenol contains:
The Keto form of phenol contains:
- A. \( 3 \pi, 13 \sigma, 4 \) non-bonding electrons
- B. \( 4 \pi, 15 \sigma, 3 \) non-bonding electrons
- C. \( 3 \pi, 14 \sigma, 4 \) non-bonding electrons
- D. \( 2 \pi, 15 \sigma, 6 \) non-bonding electrons
Step-by-step solution
The keto form of phenol is cyclohexa-2,4-dienone. It contains 2 C=C and 1 C=O double bonds, giving 3 π bonds. Sigma bonds: 6 C-C, 6 C-H, and 1 C-O total 13 σ bonds. The carbonyl oxygen has 2 lone pairs, contributing 4 non-bonding electrons.
