Cho dãy các chất: phenyl axetat, metyl axetat, etyl fomat, tripan
Giải thích
Chọn A.
Phenyl axetat
CH3COOC6H5+2NaOH→CH3COONa+C6H5ONa+H2O
Metyl axetat
CH3COOCH3+NaOH→CH3COONa+CH3OH
Etyl fomat
HCOOC2H5+NaOH→HCOONa+C2H5OH
Tripanmitin
C15H31COO3C3H5+3NaOH→3C15H31COONa+C3H5(OH)3
Vinyl axetat
CH3COOCH=CH2+NaOH→CH3COONa+CH3CHO
