With cryptand-222, Na forms an unusual compound of the formula, [Na (cryptand-222)] Na- . The large cryp ligand completely shields the Na+ . ion and prevents it combining with Na- .

Q. The solution of $N a$ in dry ether not only contains $N a_{solv.}^{+}$ and $e_{solv.}^{-}$ but also contains $N a_{solv.}^{-}$ formed by the following disproportionation reaction. $2 N a (s) N a_{solv.}^{+} + N a_{solv.}^{-}$ The large sodide ion can be stabilized by making its

cryptand-222

clatherate

complex with saticylaldehyde

complex with acetylacetone

With cryptand- $222$ , $N a$ forms an unusual compound of the formula, [ $N a$ (cryptand- $222)] N a^{-}$ . The large cryp ligand completely shields the $N a^{+}$ . ion and prevents it combining with $N a^{-}$ .

Q. The solution of Na in dry ether not only contains Nasolv. +​and esolv. −​but also contains Nasolv. −​formed by the following disproportionation reaction. 2Na(s)Nasolv. +​+Nasolv. −​ The large sodide ion can be stabilized by making its
