Compound A, `C_5H_(10)O`, forms a phenyl hyrazone, given negative Tollen's and iodoform tests and is reduced to n - pentane. What is the compound , A ?

Text Solution

Verified by Experts

Compound A forms hydrazone, so it is a carbonyl compound . It is a ketone as it does not reduce Tollens. reagent . The ketone does not have methyl group as it does not respond to iodoform test. Thus, the compound is pentanone - 3 . The structure of the compound is `CH_3CH_2COCH_2CH_3`.
