C8H8O gives 2,4-DNP and iodoform tests, not Tollens'. What is it?
APhenylacetaldehyde
B4-Methylbenzaldehyde
C2-Methylbenzaldehyde
DPhenyl methyl ketone
Answer & Solution
Correct answer: D. Phenyl methyl ketone
A positive 2,4-DNP test shows a carbonyl group, the iodoform test needs CH3CO, and no Tollens' result excludes an aldehyde, which fits acetophenone.
