Vedclass · Answer

(D) The product $X$ in the given reactions is toluene $(C_6H_5CH_3)$.$A$: Decarboxylation of $2$-methylbenzoic acid with sodalime $(NaOH + CaO)$ yields toluene.$B$: The Wurtz-Fittig reaction of chlorobenzene with methyl chloride $(CH_3Cl)$ in the presence of $Na$ and dry ether yields toluene.$C$: Reduction of $o$-cresol ($2$-methylphenol) with $Zn$ dust yields toluene.$D$: The trimerization of propyne $(CH_3-C \equiv CH)$ over a red-hot $Fe$ tube yields $1,3,5$-trimethylbenzene (mesitylene),not toluene.Therefore,$X$ cannot be prepared by reaction $D$.

$X$ can be prepared by which of the following reactions,except?
