Primary alcohol : ウィキペディア英語版 | Primary alcohol
A primary alcohol is an alcohol which has the hydroxyl group connected to a primary carbon atom. It can also be defined as a molecule containing a “–CH2OH” group. In contrast, a secondary alcohol has a formula “–CHROH” and a tertiary alcohol has a formula “–CR2OH”, where “R” indicates a carbon-containing group. Examples of primary alcohols include ethanol and butanol. Some sources include methanol as a primary alcohol, including the 1911 edition of the Encyclopædia Britannica, but this interpretation is less common in modern texts. ==See also==
* Alcohol (especially Nomenclature section for discussion on Secondary and Tertiary alcohols.) * Oxidation of primary alcohols to carboxylic acids
