Question

How to convert Ethanoic acid to benzene?

Answer 1

Conversion of ethanoic acid to benzene is a multi step process. The mechanism is as follows
CH3COOH + NaOH → CH3COONa
CH3COONa (NaOH + CaO), Heat →  CH4 + Na2CO3
CH4 + Br2 Heat → CH3Br
2CH3Br + 2 Na (Dry ether) → CH3-CH3
CH3-CH3 + Br2 (Heat) → CH3 -CH2 -Br
CH3 -CH2 -Br + Alc.KOH → CH2=CH2
CH2=CH2 + Br2/CCl4 → CHBr=CHBr
CHBr =CHBr + Alc.KOH → CH≡CH
3CH≡CH (Reduction) → C6H6 (Benzene)
