Question

Distinguish between neutralization reaction and displacement reaction

Answer 1

neutralisation reaction means when acid and base combine to give water and displacement means displacing a group in substrate with either electrophile or nucleophile

Answer 2

HI !

Neutalisation reaction :-
Acid and base react with each other to form salt and water. 
In this reaction , both acid ans base neutralize each other

Acid + Base ----> Salt + H₂O

Eg: - 
HCl + NaOH   ----> NaCl + H₂O
----------------------------------------------------------------------------------
Displacement  reaction(single displacement) is a reaction in which a more reactive metal displaces a less reactive metal from its compound.

Eg:-
Fe + CuSO₄ ------> FeSO₄ + Cu

In the case of double displacement , exchange of ions takes place :-

Eg:-
BaCl₂ + Na₂SO₄ ---------> BaSO₄ + NaCl
