1. Chapter 8 Nomenculature

2. Chemical Nomenculature A system of naming compounds. IUPAC rules are designed to name compounds. Common names: H2O-water. Ionic- metal+nometal. molecular- nonmetals. Exceptions: polyatomic ions. Practice Ex 8.1-Pg.255.

3. Types of Binary Ionic compounds: Binary: Compound in which only two elements are present. Binary ionic compound: Compound in which monoatomic +ve charged metal ions and monoatomic –ve charged nonmetal ions are present.

4. Types of Binary Ionic compounds Fixed charge binary ionic compound: Metal ion can form only one type of +ve ion. Fixed charge metals are group I A, II A,Al3+, Ga3+, Zn2+,Cd2+, Ag+ Variable charge binary ionic compound: Metal ion can form more than one type of +ve ion. Cr2+, Cr3+, Co2+, Co3+, Cu+, Cu2+, Au+, Au3+, Fe2+, Fe3+, Pb2+, Pb4+, Sn2+, Sn4+, Mn2+, Mn3+

7. Nomenculature for binary ionic compounds Fixed charged metals take the full name of the element plus the word “ion” Na+-sodium ion Variable charged metal ions take the full name of the element followed by a roman numeral( ) plus the word ion. Cu2+ - copper (II) ion. Cu2+ - copper (II) ion. Nonmetal ions=stem of the name+ ide + word” ion” Cl- chloride ion. Learn table 8.2-P.258

9. Name the following: Name the following: KCl Na2O MgF2 Be3N2 CuO Cu2O AuCl3 Mn2S3 Do Practice Ex: 8.2,8.3 P.259.

10. The ic and ous system. Higher-icLower-ous. Table 8.3 P.261.

11. Write formulas for the following: iron (III) choride: tin (II) fluoride stannic bromide auric oxide plumbous fluoride ferrous bromide ferric bromide copper(III) chloride

12. Nomenculature for ionic compounds containing polyatomic ions: Learn table 8.4- P. 263. If the polyatomic ion is +ve, its name is substituted that for metal. If the polyatomic ion is –ve, its name is substituted for the nonmetal stem plus ide.

14. Nomenculature for ionic compounds containing polyatomic ions: Na3PO4 K2CO3 Fe3(NO3)3 Co(NO3)2 Cu2SO4 Fe2 (SO4 )3 NH4CN (NH4)3 PO4

15. Ternary compound A compound containing three different elements.

17. Nomenculature for Binary Molecular Compounds A molecular compound in which only 2 nonmetals are present. 1. Name of first nonmetal used in full. 1. Name of first nonmetal used in full. 2. Stem of the name of second nonmetal + ide ending 2. Stem of the name of second nonmetal + ide ending 3. Appropriate suffix used. 3. Appropriate suffix used. Table 8. 5, P.266. Table 8. 5, P.266.

18. Name the following: CCl4 NCl3 CO P4 S6 S4 N4 S2O PF3 CF4 Exception: H2S- HCl- HCl-

19. Systematic Name A name of a compound based on IUPAC rules that conveys information about the composition of the compound.

20. Common Name Name of a compound not based on IUPAC rules and that does not convey the information about the composition of the compound. Learn table 8.6- Common Names.P.268

23. Nomenculculature for acids: Acid: A H containing compound that yields Hydrogen ions when dissolved in water. Ex: HCl, HNO3, H2SO4, HCN, H3PO4

24. Rules for Naming acids 1.Name of negative ion ends with ide. the prefix hydro + stem of the negative ion + suffix ic+ the word acid the prefix hydro + stem of the negative ion + suffix ic+ the word acid 2. Name of negative ion ends with ate Name of –ve ion less ate ending + suffix ic + word acid. Name of –ve ion less ate ending + suffix ic + word acid. 3.Name of negative ion ends with ite. Name of –ve ion less ite ending + suffix ous+ the word acid. Name of –ve ion less ite ending + suffix ous+ the word acid.

27. Name the following: Name the following acids: H2CO3 HClO3 HF HClO2 H2SO4 HClO HBr HClO4

28. Nonoxy acid Composed of H and other nonmetals other than oxygen that produce H+ in aqueous solution.

29. Oxy acid Composed of H, O, other elements that produce H+ in aqueous solution. Table 8.7:P.272:aq and dry state nomenculatures. Do Practice Ex: 8.9, 8.10-Pg. 275

32. Homework problems P.276: 1,3,9,13,15, 19, 23, 25, 27, 29, 31, 35, 37, 39, 41, 49, 51, 53, 55, 57, 61, 63, 65, 67, 71, 73, 79, 81, 83, 85, 87, 101, 103, 115, 119.
