Question

The iodoform test is not given by (A)  CH3 underset beginsmallmatrix | OH endsmallmatrix mathopC HCH3  (B)  CH3 overset beginsmallmatrix O | | endsmallmatrix mathopC CH2CH3  (C)  CH3CH2OH  (D)  CH3CH2 overset beginsmallmatrix O | | endsmallmatrix mathopC CH2CH3

Tardigrade Admin · Accepted Answer

The alcohols having the structure CH3- underset beginsmallmatrix | OH endsmallmatrix mathopC H- or ketones having the unit CH3- underset beginsmallmatrix || O endsmallmatrix mathopC H- give iodoform test. CH3CH2COCH2CH3 does not have such kind of structure, hence it will not give iodoform test.

$C H_{3} ∣ O H C H C H_{3}$

$C H_{3} C O ∣ ∣ C H_{2} C H_{3}$

$C H_{3} C H_{2} O H$

$C H_{3} C H_{2} C O ∣ ∣ C H_{2} C H_{3}$

The alcohols having the structure $C H_{3} - ∣ O H C H -$ or ketones having the unit $C H_{3} - ∣∣ O C H -$ give iodoform test. $C H_{3} C H_{2} COC H_{2} C H_{3}$ does not have such kind of structure, hence it will not give iodoform test.

CH3​∣OH​C​HCH3​

CH3​CO∣∣​CH2​CH3​

CH3​CH2​OH

CH3​CH2​CO∣∣​CH2​CH3​

The alcohols having the structure CH3​−∣OH​C​H− or ketones having the unit CH3​−∣∣O​C​H− give iodoform test. CH3​CH2​COCH2​CH3​ does not have such kind of structure, hence it will not give iodoform test.

$C H_{3} ∣ O H C H C H_{3}$

$C H_{3} C O ∣ ∣ C H_{2} C H_{3}$

$C H_{3} C H_{2} O H$

$C H_{3} C H_{2} C O ∣ ∣ C H_{2} C H_{3}$

The alcohols having the structure $C H_{3} - ∣ O H C H -$ or ketones having the unit $C H_{3} - ∣∣ O C H -$ give iodoform test. $C H_{3} C H_{2} COC H_{2} C H_{3}$ does not have such kind of structure, hence it will not give iodoform test.
