On vigorous oxidaiton by permanganate solution `(CH_(3))_(2)C=CHCH_(2)CHO` gives

Options

A. `(CH_(3))_(2) CO` and `OHC-CH_(2)-CHO`
B. `(CH_(3))_(2)-underset(OH)underset(|)C-underset(OH)underset(|)CH-CH_(2)-CHO`
C. `(CH_(3))_(2)CO` and `OHC-CH_(2)-COOH`
D. `(CH_(3))_(2)CO` and `CH_(2)(COOH)_(2)`

Answer

4

Explanation

On vigorus oxidation by permangnate solution
`(CH_(3))_(2) C=CH-CH_(2)CHO` guves `(CH_(3))_(2)CO ` and `CH_(2)(COOH)_(2)` . The C=C bond is cleared and oxidised to `-COOH,-CHO` group is also oxidised to `-COOH`.`(CH_(3))_(2)C=CH_(2)CHOoverset([O])underset(KMnO_(4))to(CH_(3))_(2)CO+underset(COOH)underset(|)overset(COOH)overset(|)(CH_(2)`
