Compounds containing CH3-CO- group give iodoform test. In addition to this, ethanol and alcohols having formula H3C-CH(.OH.)-R give positive iodoform test.

Q. The number of compounds that give positive iodoform test among the following are

$(C H)_{3} - C H (O H) - (C H)_{3}; C H_{3} - C ∣∣ O - C H_{3}$
$C H_{3} - C H_{2} - C H O; C H_{3} - C H_{2} - O H$
$C H_{3} - C H_{2} - C ∣∣ O - C H_{2} - C H_{3}; C H_{3} - C H O$

Compounds containing $C H_{3} - CO -$ group give iodoform test. In addition to this, ethanol and
alcohols having formula
$H_{3} C - C H (O H) - R$ give positive iodoform test.

Q. The number of compounds that give positive iodoform test among the following are (CH)3​−CH(OH)−(CH)3​;CH3​−C∣∣O​−CH3​ CH3​−CH2​−CHO;CH3​−CH2​−OH CH3​−CH2​−C∣∣O​−CH2​−CH3​;CH3​−CHO

Compounds containing CH3​−CO− group give iodoform test. In addition to this, ethanol and alcohols having formula H3​C−CH(OH)−R give positive iodoform test.
