Câu 4:
a) $2C{H_3}COOH + 2Na \to 2C{H_3}COONa + {H_2}$
b) $HCOOH + KOH \to HCOOK + {H_2}O$
c) $C{H_3}COOH + {C_2}{H_5}OH\underset{{{t^o}}}{\overset{{{H_2}S{O_4}d}}{\longleftrightarrow}}C{H_3}COO{C_2}{H_5} + {H_2}O$
d) $RCOOH + R'OH\underset{{{t^o}}}{\overset{{{H_2}S{O_4}d}}{\longleftrightarrow}}RCOOR' + {H_2}O$
e) ${C_2}{H_5}OH + {O_2}\xrightarrow{{men{\text{ giam}}}}C{H_3}COOH + {H_2}O$
Câu 5:
$C{H_3}COOH + {C_2}{H_5}OH\underset{{{t^o}}}{\overset{{{H_2}S{O_4}d}}{\longleftrightarrow}}C{H_3}COO{C_2}{H_5} + {H_2}O$
${C_2}{H_5}OH + {O_2}\xrightarrow{{men{\text{ giam}}}}C{H_3}COOH + {H_2}O$
$HCHO + {O_2}\xrightarrow{{xt,{t^o}}}HCOOH$
