Question

Toluene can be oxidised to benzoic acid by

• A. $H _{2} SO _{4}$
• B. $KMnO _{4}$
• C. $K _{2} Cr _{2} O _{7}$
• D. both (b) and (c)

Answer 1

Answer: (D)

both (b) and (c)

Answer 2

Both $KMnO _{4}$ and $K _{2} Cr _{2} O _{7}$ are strong oxidising agents therefore can oxidise any alkyl benzene to benzoic acid.
