Answer Details
The IUPAC names of the compounds CH3COOH and CH2=CH2 are respectively acetic acid and ethene. Acetic acid is a carboxylic acid with the formula CH3COOH, while ethene is an unsaturated hydrocarbon with the formula CH2=CH2. The IUPAC naming system is a set of rules used to give unique names to organic compounds based on their molecular structure. In this case, the IUPAC name of CH3COOH is derived from the parent alkane, which is methane (CH4). Replacing one hydrogen atom in methane with a methyl group (CH3) results in the parent chain for acetic acid, which is ethane (C2H6). The carboxyl group (-COOH) attached to the second carbon atom in the chain gives the compound its name, ethanoic acid. Similarly, the IUPAC name of CH2=CH2 is ethene, which is derived from the parent alkane, ethane, by removing one hydrogen atom from each of the two carbon atoms that form a double bond.
