30. A. An organic compound - A (C4H80) forms phenyl

hydrazone with phenyl hydrazine and reduces Fehling's

mpt any two questions:

solution. It has negative iodoform test. Identify the

organic compound A.

Methyl ethyl ketone

Explanation:

Compound 'A' forms phenyl hydrazone, so it must be a carbonyl compound. Since it also gives a negative iodoform test, so it can't be an aldehyde.

'A' on reduction gives propane. So, it must be butanone. Ketone reacts with phenyl hydrazine to form phenyl hydrazone but gives a negative iodoform test.

Thus, the correct answer is - Methyl ethyl ketone
