Question

?Using Benzene and acetic acid how can you prepare benzoic acid

Answer 1

The chemical formula of Acetic acid is: CH₃COOH

The chemical formula of Benzoic acid is : C₂H₅COOH

?Using Benzene and acetic acid how can you prepare benzoic acid 

a- Reaction between Acetic acid and ammonia to give amide

 b- Hofmann Rearrangement

Amides with no substituent on the nitrogen react with solutions of bromine or chlorine in sodium hydroxide to yield amines through loss of their carbonyl carbon by a reaction known as the Hofmann rearrangement

(C - Reaction methylamine with Nitrous acid NaNO₂/HCl (HNO₂

R-NH₂ + HNO₂ → ROH

d- Alkylation of benzene, using methanol 

 

E- Oxidation of Toluene by KMnO₄​

Toluene is oxidized with alkaline KMnO₄​ followed by acidification to form benzoic acid. Other oxidising agents that can be used are acidic KMnO₄​ , acidic K₂​Cr₂​O_7​ and dil HNO₃​ etc
