binary covalent compounds list

Naming binary (two-element) covalent compounds is similar to naming simple ionic compounds. What is the correct molecular formula for the compound, arsenic pentafluoride? 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. What is the correct molecular formula for the compound, sulfur dioxide? Rule 1. 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. Terms in this set (36) What is the correct molecular formula for the compound, chlorine dioxide? Strategy: List the elements in order according to their positions in the periodic table. Carbon monoxide is one of the few compounds that uses this prefix. 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. What is the correct molecular formula for the compound, tetraphosphorus hexaoxide? What is the correct molecular formula for the compound, dinitrogen trioxide? What is the correct molecular formula for the compound, tetraphosphorus decaoxide? What is the correct molecular formula for the compound, disulfur dichloride? 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. 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- A binary covalent compound is composed of two different elements (usually nonmetals). What is the correct molecular formula for the compound, boron trifluoride? A system of numerical prefixes is used to specify the number of atoms in a molecule. What is the correct molecular formula for the compound, carbon tetrabromide? This naming system is used only with binary, nonmetal compounds, with one exception. Take a look at the following examples to see how to use the prefixes when naming binary covalent compounds (the prefixes appear in bold). For some simple covalent compounds, we use common names rather than systematic names. Asked for: name of compound. Example \(\PageIndex{3}\): Binary Covalent Compounds. In general, the prefix mono- is rarely used. The following compound is commonly called manganese dioxide. 1 = mono- 2 = di- 3 = tri- 4 = tetra- 5 = penta- 6 = hexa- 7 = hepta- 8 = octa- 9 = nona- 10 = deca- Prefixes are used in the names of binary compounds to indicate the number of atoms of each nonmetal present. What is the correct molecular formula for the compound, selenium tetrafluoride? What is the correct molecular formula for the compound, silicon tetrachloride? The second element is named by taking the stem of the element name and adding the suffix -ide. What is the correct molecular formula for the compound, xenon difluoride? Write the name of each binary covalent compound. What is the correct molecular formula for the compound, dinitrogen dichloride? 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, chlorine monofluoride? Mono- is only used as a prefix on the second element in the formula. The following table lists the most common prefixes for binary covalent compounds. What is the correct name for the compound, ICl? SF 6; N 2 O 4; ClO 2; Given: molecular formula. 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.
