The following reaction 

4NH 2 (g) + 5O 2 (g) → 4NO(g) + 6H 2 O(g)

is an example of a 

 

(i) displacement reaction (ii) combination reaction

(iii) redox reaction (iv) neutralisation reaction

(A) (i) and (iv) 

(B) (ii) and (iii)

(C) (i) and (iii)

(D) (iii) and (iv)

 

Answer

  • Displacement Reaction : Reaction in which more reactive element takes the place of less reactive element.
  • Combination Reaction : When two or more substances react to form a single product, it is known as combination reaction.
  • Neutralisation reaction : A reaction in which acid and base react to form salt and water
  • Redox reaction: In this type of reaction, both oxidation and reduction take place simultaneously.

 

The above reaction is an example of displacement as well as redox reaction

 

So, the correct answer is (c) - (i) and (iii)
