Question

About alkali metal $-$ liquid $N{H}_3$ solution which of the following statement is not true?

• A. Blue colour due to ammoniated electrons
• B. Blue colour changes to bronze on dilution due to formation of metal clusters
• C. With increse in concentration of alkali metals paramagnetic nature decreases due to electron $-$ electron combination
• D. On heating blue colour becomes colourless due to formation of metal amide and $H_2$ gas

Answer 1

The correct option is B Blue colour changes to bronze on dilution due to formation of metal clusters

Blue colour changes to bronze with increase in concentration of alkali metal due to formation of metal clusters.
