In the reaction
`CH_3-CH=CH-CHO underset("agent")overset("oxidizing")to CH_3-CH=CH-COOH`, the oxidizing agent can be

Options

A. Alkaline `KMnO_4`
B. Acidified `K_2Cr_2O_7`
C. Benedict's solution
D. All of the above

Answer

C

Explanation

Benedict solution contains `CuSO_4`, sodium carbonate and sodium citrate which is specific for oxidation of aldehydes.
`CH_3CH = CHCHO underset("solution")overset("Benedict"(Ca^(2+)))to CH_3 -CH=CH-COOH`
