An acetal is a compound that has two -OR groups bonded to one carbon atom. In compound III, there are two -OMe groups bonded to the same carbon atom, making it an acetal. Compound I has only one -OR group attached to a carbon atom, making it a hemiacetal. Compound II has a -OH group and a -OR group attached to the same carbon atom, making it also a hemiacetal. Compound IV does not have any -OR or -OMe group attached to the same carbon atom.
