Learn prefixes used naming binary compounds with free interactive flashcards. When namingmolecular compoundsprefixes are used to dictate the number of a given element present in the compound. Why are prefixes used in naming covalent conpounds? For the second element, we always use the prefix and change the ending to -ide. Thus OsO 4 is osmium tetroxide rather than osmium tetraoxide. Mr. Causey shows you how to name some common binary covalent compounds. The compound is ionic if it is composed of a cation and an anion, or a metal and a nonmetal. When naming molecular compounds prefixes are used to dictate the number of a given element present in the compound. A few rules can be applied to name simple covalent compounds: name the left-most element in the periodic table first, add -ide to the second named element, and use prefixes for the numbers of atoms. What are the definitions of rogelia folk dance? 1.

To distinguish these compounds from each other, Greek prefixes are used to designate the numbers of atoms of one or both elements in the molecule. Binary covalent compounds—covalent compounds that contain only two elements—are named using a procedure similar to that used for simple ionic compounds, but prefixes are added as needed to indicate the number of atoms of each kind.The procedure, diagrammed in Figure 2.13 consists of the following steps: The cycloalkanes—cyclic hydrocarbons with only single bonds—are named by adding the prefix cyclo-to the name of the open-chain compound having the same number of carbon atoms as there are in the ring. In chemistry, a number of prefixes, suffixes and infixes are used to describe the type and position of the functional groups in the compound..
