Which of the following compoinds does not undergo haloform reaction ?

Options

A. `CH_(3)-underset(OH)underset(|)(CH)-CH_(3)`
B. `CH_(3)-underset(O)underset(||)(C)-CH_(3)`
C. `C_(2)H_(5)-underset(OH)underset(|)(CH)-C_(2)H_(5)`
D. `CH_(3)-underset(O)underset(||)(C)-C_(2)H_(5)`

Answer

C

Explanation

Haloform reaction is used to identify aldehydes and ketones containing at least one (Me) group linked to C atom of `C=O` group.
Alcohols containing `Meunderset(OH)underset(|)(CH)-` group are also
oxidised by haloform rection.
The reaction is given by the following compounds
(i) `CH_(3)CH_(2)OH`
(ii) `CH_(3)underset(OH)underset(|)(CH)R(2^(@)" alcohol with "-OH" at "C_(2))`
(iii) `CH_(3)underset(O)underset(||)(C)R` (Compound with `CH_(3)CO-` group)
(iv) `CH_(3)CHO`
Thus, according to the options givan, option 'c', i.e.,
`C_(2)H_(5)-underset(OH)underset(|)(CH)-C_(2)H_(5)`
will not undergo haloform reaction.
