Lesson 1 of 2
The hydroxyl group that defines the family
Alcohols are colourless liquids that mix with water and burn as fuels. This lesson fixes the one feature that makes them a family: the hydroxyl group responsible for their characteristic reactions.
What you know already
From Bromine & Alkenes you already know how a functional group dictates a reaction test. This note closes the wave on a third functional group: the hydroxyl group of the alcohols, the family behind fuels and spirits, with the naming twist that trades a final e for an ol.
Key points of understanding
- Alcohols are clear liquids that mix with water, giving neutral solutions.
- The first four members of the family serve as common fuels.
- Every alcohol carries the hydroxyl group, written -OH.
- The hydroxyl group is the part of the molecule responsible for the characteristic reactions of alcohols.
- In ethanol the -OH side chain is what characterises its chemistry, as the diagram of the molecule shows.
