  1. 9.2 NOMMENCLATURE

  2. Left to Right Binary Covalent Rules

  3. Left to Right SiO2 O2Si silicon dioxide dioxygensilicide Binary Covalent Rules

  4. Left to Right • “-ide” be back! Binary Covalent Rules

  5. Left to Right • “-ide” be back! SiO2 O2Si silicon dioxide dioxygensilicide Binary Covalent Rules

  6. Left to Right • “-ide” be back! • Junkies need their PRE-fix H2O NO dihydrogen monoxide nitrogen monoxide N2O SF6 dinitrogen monoxide sulfur hexafluoride Binary Covalent Rules

  7. Mono • Di • Tri • Tetra • Penta • Hexa • Hepta • Octa • Nona • Deca • 1 • 2 • 3 • 4 • 5 • 6 • 7 • 8 • 9 • 10 Pre---FIXES

  8. Left to Right • “-ide” be back! • Junkies need their PRE-fix • EXCLUDE MONO on first element Binary Covalent Rules

  9. A compound containing only two different types of atoms that are COVALENTLY bonded N2O What is a binary molecular compound?

  10. CCl4 • As2O3 • Br2 • H2O2 • NF3 • Carbon tetrachloride • Diarsenic trioxide • Bromine • Dihydrogen dioxide • Nitrogen Trifluoride Practice

  11. H2O • H2O2 • NH3 • N2H4 • N2O • NO • water • hydrogen peroxide • ammonia • hydrazine • nitrous Oxide • nitric Oxide dihydrogen monoxide dihydrogen dioxide nitrogen trihydride dinitrogentetrahydride dinitrogen monoxide nitrogen monoxide COMMON NAMES

  12. Element on the left does it need a prefix. If yes assign it. • Identify second element and change ending to ide. • Assign prefix to second element. Yes 2=di Dinitrogen O-oxygen = oxide 4=tetra Tetroxide Dinitrogentetroxide Using the rules for naming binary molecular compounds, describe how you would name N2O4.

  13. Acids

  14. OxyANION root – ic + Acid H2SO4 Sulfuric Acid Hydro + element-ic + acid HCl Hydrochloric Acid

  15. Binary acids contain hydrogen and one other element, they are named with the prefix hydro- and the root of the other element with the suffix –ic acid • Oxyacids contain oxygen bonded to another non-metal element, they are named based off the OXYANION that they are formed from. What is the difference between a binary acid and an oxyacid?

  16. Binary Acids

  17. Sulfate Phosphate Nitrate Carbonate Chlorate SO4 PO4 NO3 CO3 ClO3 Oxyacids

  18. Sulfate Phosphate Nitrate Carbonate Chlorate Sulfuric Acid Phosphoric Acid Nitric Acid Carbonic Acid Chloric Acid H2SO4 H3PO4 HNO3 H2CO3 HClO3 SO42- PO43- NO3- CO32- ClO3- Oxyacids

  19. Perchloric Acid • Chloric Acid • Chlorous Acid • Hypochlorous Acid • HClO4 • HClO3 • HClO2 • HClO +1 ---- -1 -2 Oxyacids

  20. H2SO3 • HNO • HClO4 • H3PO4 • Sulfurous Acid • Hyponitrous Acid • Perchloric Acid • Phosphoric Acid Practice
