erivatives of the hydrocarbons are formed, by replacing one or more hydrogen atoms by other groups referred to as functional groups An alcohol is closely related to a hydrocarbon in that it contains an Oh group in place of a hydrogen atom. Thus, methyl alcohol, CH3 OH, is a derivative of methane, CH4; and ethyl alcohol
