Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R: Assertion A: Metallic sodium dissolves in liquid ammonia giving a deep blue solution, which is paramagnetic. Reason R: The deep blue solution is due to the formation of amide. In the light of the above statements, choose the correct answer from the options given below:
(1) Both A and R are true and R is the correct explanation of A
(2) Both A and R are true but R is NOT the correct explanation of A
(3) A is true but R is false
(4) A is false but R is true
Metallic sodium dissolves in liquid ammonia to form ammoniated electrons, which are responsible for the deep blue colour and paramagnetism. The formation of amide occurs when the solution is allowed to stand or in the presence of catalysts, not the cause of the blue colour. Thus, A is true and R is false.
