a. Explain why ethanoic acid A is more acidic than ethanol B below. O // H3C-C CH3CH2OH OH A B b. Aldehyde J can react with an alcohol to give either acetal L or hemiacetal K, depending on the reaction conditions employed, (1) Identify the alcohol and reaction conditions required to synthesise acetal L and hemiacetal K in Figure 3. (ii) Discuss the mechanism for both of the reactions in Figure 3. OCH2CH3 H3C-CEH OH (0) (ii) H,C- H OCH2CH3 H3C-C-H OCH CH3 L J Figure 3 w
