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

D

Explanation

C=C bond is cleaved and oxidised to -COOH, -CHO group is also oxidised to -COOH.
`(CH_(3))_(2)C=CHCH_(2)CHO rarr (CH_(3))_(2)C=O+HOOC-CH_(2)-COOH`
