Gentle heating will produce an alcohol and liberate halide ions. To carry out tests for the presence of organic functional groups and to make accurate observations. When one of the three hydrogen atoms is replaced by alkyl or aryl group, primary amine is formed. Qualitative tests such as esterification with boric acid and subsequent flame test or oxidation to formaldehyde and its detection are unreliable, especially in the presence of ethanol. Carboxylic acid reacts with alcohol in presence of conc. The ethyl glucuronide (EtG) test is widely used to detect the presence in the urine of ethyl glucuronide, a breakdown product of ethanol, the intoxicating agent in alcohol.It can also screen for EtG in your blood, hair, and nails, but the urine test is the most widely used. Urine alcohol tests (such as EtG tests) detect the presence of alcohol metabolites, indicating consumption of alcohol, either presently or in the recent past. Tests for Amines. Blood alcohol level testing is considered the most accurate way to test for the presence of alcohol. Ester Test. sulphuric acid to form ester that is identified by the presence of a fruity smell.
