The reagent used for the separation of Acetadehyde from acetophenone is

Options

A. `NaHSO_(3)`
B. `C_(6)H_(5)NHNH_(2)`
C. `NH_(2)OH`
D. `NaOH-I_(2)`

Answer

A

Explanation

`NaHSO_(3)` gives the addition reaction with Aldehyde and only aliphatic ketone. Acetophenone is the aromatic ketone so it does not give the addition product with `NaHSO_(3)` aldehyde form the addition product with `NaHSO_(3)` which on treatment with acid or base give again aldehyde.
`RCHO + HSO_(3)Na rarr overset(OH)overset(|)underset(SO_(3)Na)underset(|)(R-C-H)overset(H^(o+)or)underset(OH^(Theta))rarr R-CHO`
`C_(6)H_(5)COCH_(3)+ NaHSO_(3) rarr` No reaction
