The correct option is C Sabatier-Senderens reaction
Catalytic hydrogenation of alkene by addition of H2 with catalyst Ni/Pt/Pd to prepare alkane is known as Sabatier-Senderens reaction.
Here, the reducing agent is H2(g).
R−CH=CH2+H2Ni⟶R−CH2−CH3
In Kolbe's electrolysis, the alkane is prepared from salts of dicarboxylic acid by decarboxylation.
R−COONa+R−COONa+H2OElectrolysis⟶R−R+2NaOH+2CO2+H2
In Wurtz reaction, alkane is prepared by reducing alkyl halide using Na in dry ether reagent.
R−X+2Na+X−Rdry ether⟶R−R+2NaX
Thus, the correct answer is (c).
