Vedclass · Answer

(C) The synthesis of alkenes involves elimination reactions. $(A)$ Treatment of alkynes with $Na$ in liquid $NH_3$ (Birch reduction) produces trans-alkenes. $(B)$ Heating alkyl halides with alcoholic $KOH$ undergoes dehydrohalogenation to form alkenes. $(C)$ Treating alkyl halides with aqueous $KOH$ results in nucleophilic substitution,producing alcohols $(R-X + KOH_{(aq)} \rightarrow R-OH + KX)$,not alkenes. $(D)$ Treating vicinal dihalides with $Zn$ metal undergoes debromination/dehalogenation to form alkenes. Therefore,option $C$ is the incorrect method for alkene synthesis.

The incorrect method for the synthesis of alkenes is:
