Question

Explain the addition and substitution reaction with the help of examples.
C2H6 undergoes substitution reaction but not addition reaction. Why?​

Answer 1

Answer:

e. g. C2H4+H2 in presence of nickel as catalyst will give us C2H6 which is saturated hydrocarbon. Addition reaction is also known as hydrogenation reaction. The reaction in which a reagent replaces an atom or a group of atoms from the reactants are called substitution reactions.
