Unsaturated hydrocarbon gives a positive test from the reagent. The purple color of the reagent changes to the colorless solution when any alkene and alkynes are present.

2) Dimethyl glyoxime reagent –

The reagent is a popular chelating regent with molecular formula – C[tex]_{4}[/tex]H[tex]_{8}[/tex]N[tex]_{2}[/tex]O[tex]_{2}[/tex]

USES  

Used in gravimetry for the determination of nickel, palladium, and platinum, many other metals.

3) Fehling’s solution –

It is a blue-colored solution of Rochelle salt and copper sulfate.
