Q. A carbonyl compound with molecular weight $ 86 $ , does not reduce Fehling’s solution, forms crystalline bisulphite derivatives and gives iodoform test. The possible compounds can be

AMUAMU 2011Aldehydes Ketones and Carboxylic Acids

Solution:

Both $2$-pentanone and $3$-methyl -$2$-butanone have molecular weight $86$, both do not reduce Fehling’s solution, form crystalline bisulphite derivatives and give iodoform test, as have $CH_3CO$ - group.
