On dissolving moderate amount of sodium ...

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.

Text Solution

Verified by Experts

The correct Answer is:
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)`.
