A) A, C and D
B) Only B
C) A, B and C
D) A and B
Correct Answer: C
Solution :
Compounds having either \[\text{C}{{\text{H}}_{\text{3}}}\overset{\begin{smallmatrix} \text{O} \\ \text{ }\!\!|\!\!\text{ }\!\!|\!\!\text{ } \end{smallmatrix}}{\mathop{\text{C}}}\,-\] group or CH3CHOH- group, give iodoform when warmed with \[{{\text{I}}_{\text{2}}}\] and NaOH, Thus, \[\text{C}{{\text{H}}_{\text{3}}}\underset{\begin{smallmatrix} \text{ }\!\!|\!\!\text{ } \\ \text{H} \end{smallmatrix}}{\mathop{\text{C}}}\,\text{HOH,C}{{\text{H}}_{\text{3}}}-\overset{\begin{smallmatrix} \text{O} \\ \text{ }\!\!|\!\!\text{ }\!\!|\!\!\text{ } \end{smallmatrix}}{\mathop{\text{C}}}\,-\text{C}{{\text{H}}_{\text{3}}}\text{,C}{{\text{H}}_{\text{3}}}-\underset{\begin{smallmatrix} \text{ }\!\!|\!\!\text{ } \\ \text{C}{{\text{H}}_{\text{3}}} \end{smallmatrix}}{\mathop{\text{C}}}\,\text{HOH}\] give iodoform when warmed with \[{{\text{I}}_{\text{2}}}\] and NaOH. (Remember, NaOl oxidises \[\text{C}{{\text{H}}_{\text{3}}}\text{C}{{\text{H}}_{\text{2}}}\text{OH}\]to\[\text{C}{{\text{H}}_{\text{3}}}\text{CHO}\], thus it gives positive iodoform test.)You need to login to perform this action.
