Question
Write the required reactions to convert lime to benzene.
✓

Answer

(i) $\underset{\text{lime}}{CaO} +3 C \longrightarrow CaC _2+ CO$
(ii) $CaC _2+2 H _2 O \xrightarrow{ H ^{+}} HC \equiv CH + Ca ( OH )_2$
(iii) $3 HC \equiv CH \xrightarrow[\text { Fe tube }]{\text { Red hot }} C _6 H _6$ (Benzene)
