Question 2 (10 points) Fischer Esterification cannot be catalyzed by base because O11 the oxygen in the carbonyl group is not nucleophilic enough to atack the alcohol carbon carbinol carbon). ã2) the carbovic acid is raciay deprotonated by thebase and the resting-date lan is not susceptible to nucleophilic allack by the alcohol oxygen 31 the water that would form in the reaction would reverse the forwand reaction consuming any ester product as it forms 41 the hydroxide ion that would form in the reaction would reverse the fonward reaction consuming any ester product as it forms Save Question 3 (10 points) Why is a bicarbonate base used in the reaction work-up instcad of a hydroxide-type base since the former produces an cnormous amount of effervescence, due to the nelcase of carbon dioxide, and the latter does not? 1) hydroxide bases release much more heat which could evaporate the product 2) hydroxide bases release hydrogen gas which is potentially haadou O 3) bicarbonate bases are stronger and neutraliae acid more efflectvly 40 bicarbonate bases are weaker and cannot catalyze the severse reaction to estertation Save Question 4 (10 points) The hydrolysis of esters in base is called 幸å½Facher esterification Save Question 5 (10 points) Which of the folowing compounds is (are) hydrolyzed to butanoic acid upon heating in the presence of water and sulfurik acid? () 1J ethyl butanoate ã2) butyl acetate Î 3) both of them 4) reiter of them Save
