WebPropan-2-ol is a secondary alcohol. Tertiary alcohols. A tertiary alcohol is one in which the hydroxyl group is attached to a carbon with no hydrogen atoms attached. This will normally mean that the hydroxyl group is joined to the same carbon atom as a branch. 2-methylpropan-2-ol is a tertiary alcohol. Multiple hydroxyl groups. Alcohols can ... WebLucas test is easy to use, hence it is a widely accepted method to differentiate primary, secondary and tertiary alcohols. Tertiary alcohol reacts with Lucas regent immediately to give a turbid solution. Secondary alcohol reacts with Lucas regent to give a turbid solution after 5-15mintues. Primary alcohol does not react with Lucas regent at all. survive vanze下载
