Naming Molecules

Naming Molecular Compounds There are several accepted ways to name molecular compounds. Molecules do not have to have empirical (lowest common multiple) formulas H 2 O 2 C 3 H 6 P 4 O 10 The most common is using prefixes for the number of each element in the molecule

Prefixes Mono- Di- Tri- Tetra- Penta- Hexa- Hepta- Octa- Nona- Deca -

Name the following: 1) As 4 O 10 2) BrO 3 3) BN 4) N 2 O 3 5) NI 3 6) SF 6 7) XeF 4

8)PCl 3 9)CO 10) PCl 5 11) P 2 O 5 12) S 2 Cl 2 13) ICl 2 14) SO 2

Write the formula 1) chlorine monoxide 2) oxygen difluoride 3) boron phosphide 4) dinitrogen monoxide 5) nitrogen trifluoride 6) sulfur tetrachloride 7) xenon trioxide

8) carbon dioxide 9) diphosphorous pentoxide 10) phosphorous trichloride 11) sulfur dioxide 12) bromine pentafluoride 13) disulfur dichloride 14) boron trifluoride
