Identifying chemical structure
WebTranscript There are three main types of chemical formulas: empirical, molecular and structural. Empirical formulas show the simplest whole-number ratio of atoms in a compound, molecular formulas show the number of each type of atom in a molecule, and structural formulas show how the atoms in a molecule are bonded to each other. WebThe functional groups without carbonyls are ethers, alcohols, and epoxides. Conversely, these groups with carbonyls are aldehydes, ketones, carboxylic acids, and carboxylic …
