Which of the following does not give benzoic acid salt on oxidation with hot alkaline `KMnO_(4)`.

Options

A. `Ph - CH_(3)`
B. `Ph - CH = CH - CH_(3)`
C. `Ph - C -= C - CH_(3)`
D. `Ph - C (CH_(3))_(3)`

Answer

D

Explanation

`{:(Ph - CH_(3) overset("Hot Alkaline KMnO"_(4))(rarr) Ph-COO^(-)),(Ph - CH = CH - CH_(3) overset("Hot Alkaline KMnO"_(4))(rarr) Ph - COO^(-)),(Ph - C -= C - CH_(3) overset("Hot Alkaline KMnO"_(4))(rarr) Ph - COO^(-)):}`
