The given compound, is a derivative of the alkane ethane in which one of the H atoms is replaced by an -OH group.
When a hydroxyl (OH) group is attached to an alkyl group (R) the compound formed is an alcohol represented by the general formula ROH. The given compound is ethanol.
Each of the organic compounds mentioned has a general formula so that we can identify the classification of a certain substance. The compound CH₃CH₂OH is an alcohol because it follows the general formula R-OH, where R is a hydrocarbon chain. In this case, the hydrocarbon chain is ethane. When a hydroxyl functional group is attached, it becomes an alcohol whose name is ethanol.
