Question

Europium and Ytterbium behave as good reducing agents in $+2$ oxidation state explain.

✓

Answer

The most stable oxidation state of lanthanoids is $+ 3$.
Hence, $Eu^{2+}$ and $Yb^{2+}$ tend to get $+ 3$ oxidation states by losing one electron.
Since they get oxidised, they are good reducing agents in $+ 2$ oxidation state.
