a. Based on
b. Draw the conjugate base of phenol (called phenoxide) including allimportant resonance structures.
c. Construct an explanation for why phenol is a stronger acid than anordinary alcohol. (You may want to consider first why phenoxide is lowerin PE than methoxide

- Can you explain how you find the answer? And the steps you took? Are they talking about Lewis or bronsted acid/base? How do you know?arrow_forwardhydrogens on a carbon adjacent to a carbonyl group are far more acidic than those not adjacent to a carbonyl group. The anion derived from acetone, for example, is more stable than is the anion derived from ethane. Account for the greater stability of the anion from acetone.
