Question

An organic compound 'X' reacts with 2, 4. DNP
and produces organge precipitate. It does not
reduce Tollen's regent. It react with I2 and
NaOH and give yellow coloured iodoform. X is
1) CH3-CH2-CHO 2) CCI3-CO-C6H5
3) CH3-CO-C2H5, 4) C2H5 -CO-C2H5

​

Answer 1

3 is the correct answer.

Aldehyde and ketone gives 2,4-DNP test.

Aldehyde can reduce tollen's reagent but ketone can't. So option 1 must be wrong.

Iodoform test can be given by only methyl ketone and methyl carbinol.

So,option 2 and 4 must be wrong.

Option 3 satisfies all the conditions.

It have methyl ketone.
