Step-by-step solution
Wurtz reaction is a coupling reaction where two alkyl halides are reacted with sodium metal in dry ether to give higher alkane. 2 R- Br Na R-R+2 NaBr In decarboxylation, a carboxyl group is removed and CO ₂ is released. R COO ⁻ Na ⁺ [ CaO , ] NaOH R- H Lindlar's catalyst has 3 components i.e. palladium-calcium carbonate, lead acetate and quinoline. Quinoline prevents complete hydrogenation of alkynes to alkane resulting in partial reduction. Electrophilic addition reaction occurs between electrophile and a nucleoph
