CN is pseudo-halide,when cyanogens are heated with alkali,the products are:

Pseudo halides are anions having resemblance with halide ions. Group I metals can form salts with pseudo halides. Pseudo halogens can acts as ligands and form coordinate complexes. Their hydrides are weakly acidic and can be prepared in analogous way as halogen hydrides are prepared. Azides, cyanides, selonocyanides are example of pseuda halides. Cyanide, CN^- is a pseudo hafide. When cyanogen is heated with alkali solution, the product are:

When anisole is heated with HI , the product is :

When anisole is heated with HI , the product is :

When silver nitrate is heated, the product are
