CHEM 1180 Fall 2012 Nomenclature Quiz A 7 SEP 12 Name_KEY_ Guard your quiz and conduct yourself properly. Molecular compounds are some of the simplest to name.Keys for Writing the Formulas for Molecular Compounds:- Write the element symbol for both elements.- Place a subscript after each element according to its prefix.Note: Dont write the subscript '1'.---------Prefixesmono- 1di- 2tri- 3tetra- 4penta- 5hexa- 6hepta- 7octa- 8nona- 9deca- 10---------Caution: We only write \"mono\" for the second element in a molecular compound. The second element, chlorine, becomes chloride, and we attach the correct numerical prefix (tetra-) to indicate that the molecule contains four chlorine atoms.Putting these pieces together gives the name carbon tetrachloride for this compound.
