Ten carbon atoms in the LCC makes the compound a derivative of decane (rule 1), and the OH on the third carbon atom makes it a 3-decanol (rule 2). Because OH is the functional group of all alcohols, we often represent alcohols by the general formula ROH, where R is an alkyl group.

Finally, we add enough hydrogen atoms to give each carbon atom four bonds. The key to understanding the physical properties of alcohols and as we shall see later, their reactivity is to appreciate just how polarized the hydroxyl group is. The second key implication of hydrogen bonding is that the hydroxyl group imparts much greater water solubility upon organic molecules. The primary alcohol 1-butanol, the secondary alcohol 2-butanol, and the tertiary alcohol 2-methyl-2-propanol are added to separate test tubes.
