      Functional group analysis is an integral part of the universitycurriculumsince it forms the basis of identification of unknownorganic compounds. Traditional methods of analyzingfunctional groups employ an excess of reagents and generateenormous waste material, disposal of which is of prime concern.The present article focuses on alternative methods forthe detection of some of the functional groups such as carboxylicacid, alcohol, phenol, carbonyl, ester, and carbohydrateswith considerably less volume (few drops) of conventionalreagents on a grooved tile. The procedures adopted arein accordance with the principles of green chemistry – consumptionof less solvents and minimizing the waste. Hence,the mentioned experiments afford an efficient, safe and economicalapproach to functional group investigation. In addition,a comparison of this micro-scale green approach withconventional methods is presented. The success of the tests isvalid for general organic compounds, and hence can be satisfactorilyemployed in undergraduate laboratories for analysisof functional groups.
