pre built kit homes victoriaĪ test to distinguish between ethanol and methanol Web2,4-DNP Test for Aldehydes and Ketones. Iodine solution is added to a small amount of an alcohol. This is chemically the more obvious method. There are two apparently quite different mixtures of reagents that can be used to do this reaction, but are chemically equivalent. WebThe triiodomethane (iodoform) reaction can be used to identify the presence of a CH 3CH(OH) group in alcohols. 2-pentanone and 3-pentanone can be distinguished by iodoform test as 2-pentanone gives iodoform reaction but 3-pentanone doesn’t give iodoform reaction. Q) How can you distinguish 2-pentanone and 3-pentanone.
