I've learned esters & carbo acids are funct group isomers, so are cycloalkanes & alkenes, ketones & aldehydes;
and alcohols & ethers, but ethers isn't really in the syllabus range yet they do count as funct group isomers, so if there's a question on the no. of funct isomers of an alcohol, should we consider ethers
