Question

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 (A)  2 -pentanone and 3 -pentanone (B)  2 -pentanone and 3 -methyl- 2 -butanone (C)  2 -pentanone and pentanal (D)  3 -pentanone and 3 -methyl- 2 -butanone

Tardigrade Admin · Accepted Answer

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 CH3CO - group.

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

$2$ -pentanone and $3$ -pentanone

$2$ -pentanone and $3$ -methyl- $2$ -butanone

$2$ -pentanone and pentanal

$3$ -pentanone and $3$ -methyl- $2$ -butanone

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 $C H_{3} CO$ - group.
