Tertiary butyl benzene does not give benzoic acid when oxidised with `KMnO_(4)`. Why?

Why 3^@ -butyl benzene does not give benzoic acid on oxidation with hot alkaline KMnO_4 ?

Tert - Butylbenzene does not give benzoic acid on treatment with acidic KMnO_4 - Explain.

Statement 1: tert-Butybenzene on oxidation does not give benzoic acid on oxidation with acidic KMnO_(4) . Statement 2: Due to the absence of benzylic hydrogen.

Statement 1: tert-Butybenzene on oxidation does not give benzoic acid on oxidation with acidic KMnO_(4) . Statement 2: Due to the absence of benzylic hydrogen.

Assertion : Tertiary butyl benzene on oxidation give benzoic acid. Reason : A side chain containing benzylic hydrogen atom is oxidised to -COOH group.
