Iodoform test. It works because ethanol is oxisidised to ethanal in the rxn, which answers iodoform.

IODOFORM TEST

the alcohol is reacted with iodine and NaOH which gives a yellow precipitate of methyl iodide..

if the alcohol contains methyl grp on alpha carbon, it will give ppt..othrwsie not!!!

so only ethyl alcohol answers this test..

U r wrong. Iodoform is used to find CH3CO- group n not methyl group.
