a) the compound is a functionalized hydrocarbon since it contains oxygen in addition to carbon and hydrogen. It has an $-COOH$ group, so it is a carboxylic acid b) the compound is a functionalized hydrocarbon since it contains oxygen in addition to carbon and hydrogen, it is an aldehyde ($CHO$ group) c) the compound is a hydrocarbon d) the compound is a functionalized hydrocarbon since it contains oxygen in addition to carbon and hydrogen. It has a general formula of $R-O-R'$ , so it is an ether
