Question
Compound with molecular formula $C _4 H _8 O$ reacts with hydrazine and gives hydrazone. It forms iodoform by the reaction with iodine and NaOH but does not react with Fehling solution. Give the structure of this compound and required equations.
✓

Answer

Compound reacts with hydrazine so this is carbonyl compound but it does not react with Fehling solution so this will be ketone and forms iodoform so this is butanone $\left( CH _3 COCH _2- CH _3\right)$, methyl ketone which is proved by molecular formula. Equations of above reactions are as under :
