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.Choose the correct answer from the options given below:
Both A and R are true and R is the correct explanation of A.
Both A and R are true and R is NOT the correct explanation of A.
A is true but R is false.
A is false but R is true.
To solve this problem, we need to analyze both the assertion and the reason given in the question.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.Let's evaluate each statement:• Assertion A is true. When metallic sodium is dissolved in liquid ammonia, it forms a deep blue solution. This is due to the presence of solvated electrons, which are unpaired and hence, paramagnetic.• Reason R is false. The deep blue color is not due to the formation of amide. Instead, it is due to the presence of solvated electrons in the solution.Therefore, the correct answer is:Option 3: A is true but R is false.
