Alkali metals readily dissolve in liquid ammonia to give blue coloured solutions. The blue colour is believed to be due to

• A

  ammoniated cations
• B

  ammoniated anions
• Correct answer
  C

  ammoniated electrons
• D

  ammoniated cations and ammoniated electrons

Solution

Alkali metals readily dissolve in liquid ammonia. It gives blue coloured solution due to ammoniated electrons. The reaction is shown below :

Hence, the correct answer is option: 'C'.
