At higher temperature, iodoform reaction is given by

Only ${\mathrm{CH}}_3{\mathrm{COOC}}_2{\mathrm{H}}_5$ will give ethanol, after hydrolysis (which can give positive iodoform test).

${\mathrm{CH}}_3{\mathrm{COOC}}_2{\mathrm{H}}_5 \stackrel{{\mathrm{H}}_2\mathrm{O}}{\rightleftharpoons }$${\mathrm{CH}}_3\mathrm{COOH} +{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}$

Ethyl alcohol gives idoform test
