  1. Chapter 6 Section 5 Binary Molecular Compounds -made up of two non-metals Ex- CO, CO2, CCℓ4 -to name molecular compounds you use prefixes

  2. Prefix# (subscript) mono- 1 di- 2 tri- 3 tetra- 4 penta- 5 hexa- 6 hepta- 7 octa- 8 nona- 9 deca- 10

  3. Naming Molecular Compounds -look at subscript of each element and give each element a prefix -if first element has a 1 as the subscript, then it does not get a prefix (omit mono-) -second element gets prefix and ends in –ide -if element begins with a vowel, drop the vowel at the end of a prefix **when writing formulas for molecular compounds you DO NOT reduce subscripts

  4. Try these!! carbon monoxide CO carbon tetrachloride CCℓ4 sulfur trioxide SO3 tetraiodinenonoxide I4O9 phosphorus pentafluoride PF5

  5. N2O PCℓ3 SF6 OF2 CℓO8 NF3 S2Cℓ2 N2O4

  6. dinitrogen monoxide phosphorous trichloride sulfur hexafluoride oxygen difluoride chlorine octoxide nitrogen trifluoride disulfur dichloride dinitrogentetroxide

  7. Acids -acids are compounds dissolved in water -will have (aq) after the formula which means aqueous or dissolved in water -always begin with hydrogen (H) Ex- HCℓ H2SO4 H3PO3 Naming Acids -you must look at what follows the hydrogen

  8. -if it is a single element (ends in –ide), then you use prefix hydro-, root of the element, -ic ending and the word acid ex- HCℓ hydrochloric acid -if what follows hydrogen ends in –ite, you just add –ous ending to root of the polyatomic ion and add acid ex- H3PO3 phosphorous acid

  9. -if what follows hydrogen ends in –ate, you just add –ic ending to root of the polyatomic ion and add acid ex- H2SO4 sulfuric acid Try these!! HI hydroiodic acid H2S hydrosulfuric acid H2CO3 carbonic acid

  10. sulfurous acid H2SO3 nitrous acid HNO2 chloric acid HCℓO3
