Chapter 17, Problem 17.11YT

Interpretation Introduction

Interpretation:

The two electron-deficient sites in $\begin{array}{l}\text{cyclohex-2-en-1-one}\hfill \end{array}$ are to be identified, and the $\text{α}$ and $\text{β}$ carbons are to be labeled for the same.

Concept introduction:

In carbonyl compounds, the carbonyl group is polar, and the carbonyl carbon is electron-deficient while carbonyl oxygen is electron-rich due to the electronegativity difference. In the case of $\text{α,β-unsaturated}$ carbonyl compounds, in addition, $\text{βC}$ also appears on the electron-deficient side due to resonance. The $\text{α}$ carbon is carbon next to the carbonyl carbon, and $\text{β}$ is the carbon that is attached next to the $\text{α}$ carbon.
