On dissolving moderate amount of sodium metal in liquid ammonia at low

1.	On dissolving moderate amount of sodium metal in liquid ammonia at low temperature, which of the following does not occur ?A. Blue colored solution is not obtained.B. `Na^(+)` ions are formed in the solution.C. Liquid `NH_(3)` remains diamagnetic.D. Liquid `NH_(3)` becomoes a good conductor of electricity.
Answer» Correct Answer - C Solution of Na metal in liquid `NH_(3)` consists of solvated `Na^(+)` ions solvated electrons. Due to the presence of solvated electrons, liquid `NH_(3)` is no longer diamagnetic. If becomes paramagnetic: `Na+(x+y)NH_(3)rarrNa^(+)(NH_(3))+e^(-)(NH_(3))_(y)`.
