how to prepare for organic tests effectively!!?? pls suggest a method

Organic compounds unlike the inorganic ones cannot be identifeid by testing the ions as they do not give ions in the solution because of having colvalent linkages in them.Organic compounds can be generally identified by studying their physical and chemical properties which are the properties of the functional group present in them.Preliminary examination like state,appearence,colour solubility and odour help you identifying many organic compounds. Like,aldehydes,ketones,ethers,carbohydrates all are colourless.Compounds containig nitro group,iodiform are yellow.And lastly remember the test for functional groups properly.
