The reagent that can be used to convert butane -2-one to propanoic acid is

Options

A. `NaOH, NaI//H^(+)`
B. Fehling solution
C. Tollens reagent
D. `NaOH, I_2//H^(+)`

Answer

D

Explanation

Butanone is `CH_3 CH_2COCH_3`. It contains `-COCH_3` group which can be converted to -COOH by carrying out the iodoform test. The reagent used is NaOH, `I_2//H^(+)`.
`CH_3CH_2COCH_3 + underset((underset("and "OH^(-))("from "I_2)))(3OI^(-)) rarr CH_3CH_2COO^(-)+CHI_3 +2OH^(-)`
