a. Which alkali metal is used as a coolent in nuclear reactor ?
b. What is the oxidation state of K in `KO_(2)` ?
c. The `E^(Θ)` for `CI_(2)CI^(Θ)` is `+1.36`, for `I_(2)//I^(Θ)` is `+0.53`, for `Ag^(o+)//Ag` is `+0.79`, for `Na^(o+)//Na` is `-2.71` and for `Li^(o+)//Li` is`-3.04`. Arrange the following ionic species in decreasing order of reducing strength.
`I^(Θ), Ag, CI^(Θ), Li, Na`
d. Why is `KO_(2)` is paramagnetic ?

Text Solution

Verified by Experts

a. Sodium
b. The superoxide species respresented as `O_(2)^(Θ)` . Since the compound is netural, therefore the oxidation state of potassium is +1.
c. The order is `LigtNagtI^(Θ)gtAggtCI^(Θ)`.
d. The superoxide `O_(2)^(Θ)` is paramagnetic, because of one unpaired electron in `pi^(*)2p` antibonding molecular orbital.
