A compound (A) `C_(5)H_(10) Cl_(2)` on hydrolysis gives `C_(5)H_(10)O` which reacts with `NH_(2)OH`, forms iodoform but does not give Fehling test (A) is :

Options

A. `CH_3-underset(Cl)underset(|)overset(Cl)overset(|)C-CH_2-CH_2-CH_3`
B. `CH_3CH_2-underset(Cl)underset(|)overset(Cl)overset(|)C-CH_2CH_3`
C. `CH_3CH_2CH_2CH_2 underset(Cl)underset(|)overset(Cl)overset(|)(CH)`
D. `CH_3-overset(Cl)overset(|)(CH)-overset(Cl)overset(|)(CH)-CH_2-CH_3`

Answer

A

Explanation

As A reacts with hydroxylamine it means A may be aldehyde or ketone, but it does not react with Fehling solution hence A must be a ketone. Secondly it forms iodoform which is a characteristic reaction of methyl ketone.
