Question

Scrieti ecuatiile acizilor de estetificare dintre:acidul formic si metanol,acidul butanoic si acidul 1 butanol,acidul cetic si 1 propanol,acidul metanoic si propinoic,acidul etanoic si metanol.Denumiti esterii obtinuti!Pls

Answer 1

1).HCOOH + CH3-OH -> HCOO-CH3 + H2O
2).CH3-CH2-CH2-COOH + CH3-CH2-CH2-CH2-OH ( 1-butanol ) -> CH3-CH2-CH2-COO-CH2-CH2-CH2-CH3 + H2O
3).CH3-COOH + CH3-CH2-CH2-OH -> CH3-COO-CH2-CH2-CH3 +H2O
4).HCOOH + CH3-CH2-CH2-OH -> HCOO-CH2-CH2-CH3 + H2O
5).CH3-COOH + CH3-OH -> CH3-COO-CH3 + H2O.

Reactiile de esterificare nu pot avea loc intre 2 acizi carboxilici, ci doar intre acizi carboxilici sau derivati functionali ai acestora ( halogenuri de alchil, anhidride ) si alcooli sau derivati functionali si fenoli! ☺
