Distinction among 1 °, 2 ° and 3 ° Alcohols
1 °, 2 ° and 3 ° alcohols are distinguished by Lucas test, oxidation and reduced copper.
Victor Meyer’ s test is also used to distinguish them.
In this test, primary( 1 °) alcohols give red colour, secondary( 2 °) alcohols give blue colour and tertiary( 3 °) alcohols give no colouration.
