do tertiary alcohols react with sodium solution

reactivity of alcohols?

31 07 2009And since we al know that alkyl groups are electron donating which type of alcohol do you think is the most acidic (most acidic = more reactive with sodium metal) - Hint - the answer is 'primary' -) Btw all three types of alcohols will react with sodium metal and produce very stong alkoxide bases

Oxidation of Alcohols

In the oxidation test the alcohols are oxidized with sodium dichromate (Na 2 Cr 2 O 7) The rate of oxidation varies between primary secondary and tertiary alcohol On the basis of their oxidation rates alcohols can be distinguished as: Primary alcohol gets easily oxidized to an aldehyde and can further be oxidized to carboxylic acids too
