what do you understand by trivial names of compound
Answers
Generally, trivial names are not useful in describing the essential properties of the thing being named. Properties such as the molecular structure of a chemical compound are not indicated. And, in some cases, trivial names can be ambiguous or will carry different meanings in different industries or in different geographic regions. (For example, a trivial name such as white metal can mean various things.) On the other hand, systematic names can be so convoluted and difficult to parse that their trivial names are preferred. As a result, a limited number of trivial chemical names are retained names, an accepted part of the nomenclature.
Trivial names often arise in the common language; they may come from historic usages in, for example, alchemy. Many trivial names pre-date the institution of formal naming conventions. Names can be based on a property of the chemical, including appearance (color, taste or smell), consistency, and crystal structure; a place where it was found or where the discoverer comes from; the name of a scientist; a mythological figure; an astronomical body; the shape of the molecule; and even fictional figures. All elements that have been isolated have trivial names.
