WebThe empirical formula of a chemical compound represents the ratio of the elements present in that compound. Empirical formulae are usually obtained based on the analysis of experimental data. The empirical formula for glucose is CH 2 O. Empirical Formulae can be derived from the molecular formulae. Structural Formula: WebAn ester is a chemical compound derived from an acid (organic or inorganic) in which at least one –OH hydroxyl group is replaced by an –O– alkyl (alkoxy) group. To put it in simple terms, esters are a group of chemical compounds which are formed by bonding of an alcohol group with a group of organic acids, by losing water molecules.
