A binary covalent compound is composed of two different elements (usually nonmetals). Organic compounds are compounds with carbon atoms and are named by a separate nomenclature system that we will introduce in Section 4.6 … What is the correct molecular formula for the compound, xenon difluoride? What is the correct molecular formula for the compound, selenium tetrafluoride? What is the correct molecular formula for the compound, disulfur dichloride? What is the correct molecular formula for the compound, chlorine monofluoride? For example, N2O4 is referred to as dinitrogen tetroxide, not dinitrogen tetraoxide, and CO is … A system of numerical prefixes is used to specify the number of atoms in a molecule. In general, the prefix mono- is rarely used. Use the appropriate prefixes to name these simple compounds. What is the correct molecular formula for the compound, tetraphosphorus hexaoxide? What is the correct molecular formula for the compound, dichlorine monoxide? For some simple covalent compounds, we use common names rather than systematic names. What is the correct molecular formula for the compound, sulfur tetrafluoride? Prefixes are used in the names of binary compounds to indicate the number of atoms of each nonmetal present. The following compound is commonly called manganese dioxide. Take a look at the following examples to see how to use the prefixes when naming binary covalent compounds (the prefixes appear in bold). If a binary compound is composed of two nonmetals, it is a covalent/molecular compound. Note that chemists try to avoid putting an a and an o together with the oxide name, as in decaoxide, so they normally drop the a off the prefix. What is the correct molecular formula for the compound, carbon tetrabromide? How to Find and Number the Longest Chain in a…, How to Distinguish between Primary and Secondary Crime Scenes, How to Interpret a Correlation Coefficient r. Binary covalent compounds are compounds made up of only two elements, such as carbon dioxide. What is the correct molecular formula for the compound, tetraphosphorus decasulfide? What is the correct name for the compound, IF, What is the correct name for the compound, NF, What is the correct name for the compound, NO, What is the correct name for the compound, CF, What is the correct name for the compound, N, What is the correct name for the compound, P, What is the correct name for the compound, SeF, What is the correct name for the compound, PCl, What is the correct name for the compound, SF, What is the correct name for the compound, SO, What is the correct name for the compound, S, What is the correct name for the compound, XeF, What is the correct name for the compound, CS. This naming system is used only with binary, nonmetal compounds, with one exception. The following table lists the most common prefixes for binary covalent compounds. Strategy: List the elements in order according to their positions in the periodic table. What is the correct molecular formula for the compound, chlorine dioxide? 1 = mono- 2 = di- 3 = tri- 4 = tetra- 5 = penta- 6 = hexa- 7 = hepta- 8 = octa- 9 = nona- 10 = deca- SF 6; N 2 O 4; ClO 2; Given: molecular formula. For example, a molecule of chlorine trifluoride, ClF, What is the correct name for the compound, AsF, What is the correct name for the compound, B, What is the correct name for the compound, BrF. What is the correct molecular formula for the compound, tetraphosphorus decaoxide? What is the correct molecular formula for the compound, disulfur decafluoride? What is the correct molecular formula for the compound, xenon trioxide? What is the correct molecular formula for the compound, nitrogen trichloride? The second element is named by taking the stem of the element name and adding the suffix -ide. The first element in the formula is simply listed using the name of the element. The ending for the second element is always removed and replaced with -ide. What is the correct molecular formula for the compound, tetraphosphorus trisulfide? What is the correct name for the compound, ClF? We have already encountered these compounds, but we list them here explicitly: H 2 O: water; NH 3: ammonia; CH 4: methane; Methane is the simplest organic compound. What is the correct molecular formula for the compound, dinitrogen pentoxide. Rule 1. What is the correct molecular formula for the compound, dinitrogen dichloride? Naming binary (two-element) covalent compounds is similar to naming simple ionic compounds. What is the correct molecular formula for the compound, sulfur dioxide? The nomenclature of binary covalent compounds follows these rules: These examples show how the rules are applied for the covalent compounds formed by nitrogen and oxygen: To avoid awkward pronunciations, the final o or a of the prefix is often dropped when the element name begins with a vowel. The element with the lower group number is written first in the name; the element with the higher group number is written second in the name. What is the correct molecular formula for the compound, boron trifluoride? What is the correct molecular formula for the compound, arsenic pentafluoride? For example, a molecule of chlorine trifluoride, ClF3contains 1 atom of chlorine and 3 atoms of fluorine. Mono- is only used as a prefix on the second element in the formula. Common Prefixes for Binary Covalent Compounds; Number of Atoms Prefix; 1: mono-2: di-3: tri-4: tetra-5: penta-6: hexa-7: hepta-8: octa-9: nona-10: deca- What is the correct name for the compound, ICl? What is the correct molecular formula for the compound, silicon tetrachloride? Make use of the prefixes mono (for the second element only), di-, tri-, tetra-, penta-, hexa-, hepta-, octa-, nona- and deca- to associate the formulae of various binary covalent compounds with their names. Example \(\PageIndex{3}\): Binary Covalent Compounds.
