Baeyer's reaction

When alkenes are oxidised with cold, alkaline KMnO4, dihydroxy compounds (diols or glycols) are formed. The KMnO4 gets decolorized. This reaction is therefore, used as Bayer's test for unsaturation (the presence of double or triple bonds) in any molecule.

Ethene gives ethane-1,2-diol.

Bayer s test is to check the presence of double or triple bonds

ethane ethane-1,2-diol
