Explain the following : (a) Esters can be prepared by the reaction of RCOOH and R'X in basic medium. Why is this method not suitable for the preparation of t-butyl ethanoate ? (b) How is t-butyl ethanoate prepared ? ( c) Explain the rate esterification of the following acids with MeOH . (d) Why cannot HCl be used for the conversion of RCOOH to RCOCl ? ( e) Why can esters be prepared more efficiently by the squence : RCOOH rarr RCOCl rarr RCOOR' , rather than RCOOH rarr RCOOR' ? (f) Why are acyl azides less reactive than ROCOCl but a little more reactive than anhydride ? K_a of N_3 H = 2.6 xx 10^-5 and K_a of CH_3 COOH = 1.8 xx 10^-5 .
