Produces sodium amide
Shows blue colour
Exhibits electrical conductivity
Produces hydrogen gas
- Poorest reducing agent
- Strongest oxidising agent
- Strongest reducing agent
- Poorest oxidising agent
- The solutions are good conductor of electricity and main current carriers are solvated electrons
- On standing, the solution slowly liberates H2 gas
- NaNH2 can be conveniently prepared by treatment of Na with liquid NH3 in presence of a trace of FeCl3
- All of the above
- 1%

Read the following and select one the correct answer:
Statement I: Alkali metals dissolve in liquid ammonia to give a blue solution
Statement II: Alkali metals dissolve in liquid ammonia to give solvated species of the type [M(NH3)n]+
Statement I and Statement II are both correct. Statement II correctly explains Statement I
Statement I and Statement II are both correct. Statement II does not explain Statement I
Statement II is correct and Statement I is wrong
Statement I is correct and Statement II is wrong
