  1. PRENTICE HALLChemistry Ch. 9 “IUPAC” Inorganic Nomenclature

  2. WHAT IS NOMENCLATURE?

  3. INORGANIC NOMENCLATURE

  4. WE WILL BE EMPLOYING THE “IUPAC” RULES I U P A C

  5. BinaryIonic Compounds 01. WHAT IS A BINARY IONIC COMPOUND? METAL – NONMETAL w/ just 2 types of ions 02. DO YOU REMEMBER HOW (A METHOD) TO WRITE A BALANCED IONIC FORMULA? Ca+2 (PO4)-3 CRISS-CROSS METHOD 3 2 03. IS ANYONE FAMILIAR WITH HOW BINARY IONIC COMPOUNDS ARE NAMED? NAME OF METAL, NAME OF NONMETAL w/ -ide ending (suffix).

  6. BinaryIonic Compounds EXAMPLES: Mg+2 magnesium andF- fluorine MagnesiumfluorideMgF2 Na+ sodium andO2- oxygen SodiumoxideNa2O

  7. CAVEATS with IONICS… ????????????????

  8. Binary Ionic Compounds with MultipleValence METALS FormulaStock MethodCLASSIC/LATIN Name FeF2Iron (II) Fluoride Ferrous Fluoride FeF3Iron (III)Fluoride Ferric Fluoride +1 +2 +3 +/-4 -3 -2 -1

  9. Binary Ionic w/ MultipleValencesTRY THE FOLLOWING… FormulaStock MethodCLASSIC/LATIN Name HgBr HgBr2 +1 +2 +3 +/-4 -3 -2 -1 ROMAN NUMERALS NEEDED

  10. Binary Ionic w/ MultipleValencesTRY THE FOLLOWING… FormulaStock MethodCLASSIC/LATIN Name HgBr Mercury (I) Bromide HgBr2 +1 +2 +3 +/-4 -3 -2 -1 ROMAN NUMERALS NEEDED

  11. Binary Ionic w/ MultipleValencesTRY THE FOLLOWING… FormulaStock MethodCLASSIC/LATIN Name HgBr Mercury (I) Bromide HgBr2 Mercury (II) Bromide +1 +2 +3 +/-4 -3 -2 -1 ROMAN NUMERALS NEEDED

  12. Binary Ionic w/ MultipleValencesTRY THE FOLLOWING… FormulaStock MethodCLASSIC/LATIN Name HgBr Mercury(I)Bromide Mercurous Bromide HgBr2 Mercury(II)Bromide Mercuric Bromide ODDLY ENOUGH… Hg is an abbreviation of the Latin name for Mercury… Hydrargium.

  13. Binary Ionic Compounds with Multiple Valences PLEASE COMPLETE THE CHART CompoundIUPAC NAMECommon Name FeF2 Ferrous Fluoride FeF3 Ferric Fluoride Mercury(I)Bromide Mercurous Bromide Mercury(II)Bromide Mercuric Bromide

  14. Binary Ionic Compounds with Multiple Valences CompoundStock MethodCommon Name FeF2 Iron (II) Fluoride Ferrous Fluoride FeF3 Iron (III)Fluoride Ferric Fluoride HgBr Mercury(I)Bromide Mercurous Bromide HgBr2 Mercury(II)Bromide Mercuric Bromide

  15. NAME THESE Sr3O2 PbCl4 PbO2

  16. PROVIDE FORMULAS Potassium Nitride Aluminum fluoride Vanaduim (III) chloride

  17. Tests for Iron (II) and Iron (III) Ions Introduction:  Some transition metals can form cations with more than one charge.  Iron is an example of such a metal.  It forms the ferrous, or iron (II), ions which have a +2 charge.  It also forms the ferric, or iron(III), ions which have a +3 charge.  In this lab you will learn how to test a compound to determine whether it contains iron (II) or iron (III).  These tests will be useful if you need to identify and write the formula for an iron-containing compound.

  18. TernaryIonic Compounds FormulaIonsName Ca(NO3)2 Ca+2 and NO31- Calcium Nitrate Ca(NO2)2 Ca+2 and NO21- Calcium Nitrite The system does not change with multiple valence cations! Fe(NO3)2 Fe2+ and NO31- Iron (II)Nitrateor FerrousNitrate

  19. TRY A FEW MgCO3 NaClO3 Al2(Cr2O7)3 CuCr2O7

  20. PRACTICE TIP Formulas with more than two symbols… Skip the first symbol, and place a parenthesis around the rest! ( ) Na C2H3O2

  21. THUS FAR… ????????????????

  22. ThePolyatomicAnions IONName IONName NO31- Nitrate ClO41- Perchlorate NO21- Nitrite ClO31- Chlorate SO32- Sulfite ClO21- Chlorite SO42- Sulfate ClO1- Hypochlorite HSO41- HydrogenSulfate (orBisulfate) (Still SO4-2… but reduced by H+1) You’ll have to “LOOK THESE UP” until they become more familiar. Don’t memorize… familiarize… decode systems & recognize patterns!!!

  23. Some Polyatomic Anions You Just Can’t Find... SeO4-2IO3-IO- Let the TABLE be your guide !!! SO4-2 = sulfate… SeO4-2 = selenate ClO3- = chlorate… IO3- = iodate ClO- = hypochlorite… IO- = hypoiodite ARE YOU WITH ME?… Which polyatomic anions are necessary for agriculture and plant reproduction? GeO3-2 germinate and pollinate PoO4-2

  24. Ionic Compound ISSUES NOTE: the -ide ending for an anion name is reserved for “mono-element” anions with a few extremely important exceptions. OH- = hydroxide CN- = cyanide O22- = peroxide COMPOUND EXAMPLE: NH4OH

  25. ASSIGNMENT:page 266 #14-19

  26. ACID NOMENCLATURE How do you know a formula is that of an ACID? Starts with “H” What 2 types of ACID formulas will we name? BINARY: HCl, H2S, H3N… TERTIARY: HClO3, H2SO4, HNO3…

  27. ACID NOMENCLATURE TERNARY(oxyacids) H __ __ __ … BINARY H __ “Hydro” ______ic Acid “-ate groups” form “-ic acids” “-ite groups form - -“ous acids” HCl Hydrochloric Acid HNO3 contains nitrate Nitric acid HNO2 contains nitrite Nitrous acid H2S Hydrosulfuric Acid

  28. FIND “IUPAC” NAMES:HBrHIHIO3HIO2H2SO4

  29. WRITE FORMULAS:hydrosulfuric acidhydrofluoric acidbromic acidbromous acidhypobromous acid

  30. ASSIGNMENT:page 273 #26-33

  31. This lab activity requires mixing ionic compounds, determining AND naming products… and writing equations to represent the formation of each precipitate

  32. FINALLY…THE LAST TYPE OF COMPOUND TO NAME NON-METALS with NON-METALS

  33. MOLECULARCOMPOUNDS FormulaSystematic NameCommon Name NO Nitrogen Monoxide Nitric Oxide N2O Dinitrogen Monoxide Nitrous Oxide NO2 Nitrogen Dioxide Nitrogen Peroxide N2O5 Dinitrogen Pentoxide Nitric Anhydride N2O3 Dinitrogen Trioxide Nitrous Anhydride

  34. ASSIGNMENT:page 270 #20-25

  35. ASSIGNMENT:RESEARCH AN INORGANIC COMPOUNDCREATE A 3 SLIDE PRESENTATIONFeature its: formula, IUPAC name, common name, uses, value, availability (how/where it is obtained), any hazardous and/or legal issues, etc. http://en.wikipedia.org/wiki/List_of_inorganic_compounds

  37. PRACTICE… Provide IUPAC NAMES Common NameChemical Formula a. Sugar of lead Pb(C2H3O2)2 b. Blue vitrol CuSO4 c. Epsom salts MgSO4 d. Milk of magnesia Mg(OH)2 e. Gypsum CaSO4 f. Laughing Gas N2O
