Đáp án C
C 6 H 5 COOC 6 H 5 + 2 NaOH → t ° C 6 H 5 COONa + C 6 H 5 ONa + H 2 O
CH 3 COO - [ CH 2 ] 2 - OOCCH 2 CH 3 + 2 NaOH → t ° CH 3 COONa + OH – CH 2 – CH 2 – OH + CH 3 CH 2 COONa
CH 3 OOC - COOCH 3 + 2 NaOH → t ° NaOOC – COONa + 2 CH 3 OH ( chỉ thu 1 muối )
CH 3 COOC 6 H 5 + 2 NaOH → t ° CH 3 COONa + C 6 H 5 ONa + H 2 O
