 CH3--CH2--OH

IS THE OONLY PRIMARY ALCOHOL

GIVING +VE IODOFORM TEST

REASON:

AFTER TREATING WITH I2/NaOH

IT FIRST OXIDIZED TO ETHANAL WHICH FURTHER GIVES (+)  iodoform test.

The iodoform reaction is given by compounds with a methyl group next to a carbonyl group. Secondary alcohols with a CH3 on the carbon carrying the OH (eg propan-2-ol) that can be oxidised to carbonyl compounds of this type, also give a positive iodoform test. (NB carboxylic acids do not)
