Nomenculature

chemical nomenculature
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.
types of binary ionic compounds
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.
types of binary ionic compounds1
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+
nomenculature for binary ionic compounds
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.
  • Nonmetal ions=stem of the name+ ide + word” ion”
  • Cl- chloride ion.
  • Learn table 8.2-P.258
name the following
Name the following:
  • KCl Na2O
  • MgF2 Be3N2
  • CuO Cu2O
  • AuCl3 Mn2S3
  • Do Practice Ex: 8.2,8.3 P.259.
the ic and ous system
The ic and ous system.
  • Higher-ic
  • Lower-ous.
  • Table 8.3 P.261.
write formulas for the following
Write formulas for the following:
  • iron (III) choride: tin (II) fluoride
  • stannic bromide auric oxide
  • plumbous fluoride ferrous bromide
  • ferric bromide copper(III) chloride
nomenculature for ionic compounds containing polyatomic ions
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.
nomenculature for ionic compounds containing polyatomic ions1
Nomenculature for ionic compounds containing polyatomic ions:
  • Na3PO4 K2CO3
  • Fe3(NO3)3 Co(NO3)2
  • Cu2SO4 Fe2 (SO4 )3
  • NH4CN (NH4)3 PO4
ternary compound
Ternary compound
  • A compound containing three different elements.
nomenculature for binary molecular compounds
Nomenculature for Binary Molecular Compounds
  • A molecular compound in which only 2 nonmetals are present.
  • 1. Name of first nonmetal used in full.
  • 2. Stem of the name of second nonmetal + ide ending
  • 3. Appropriate suffix used.
  • Table 8. 5, P.266.
name the following1
Name the following:
  • CCl4 NCl3
  • CO
  • P4 S6
  • S4 N4 S2O
  • PF3 CF4
  • Exception: H2S-

HCl-

systematic name
Systematic Name
  • A name of a compound based on IUPAC rules that conveys information about the composition of the compound.
common name
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
nomenculculature for acids
Nomenculculature for acids:
  • Acid: A H containing compound that yields Hydrogen ions when dissolved in water.
  • Ex: HCl, HNO3, H2SO4, HCN, H3PO4
rules for naming acids
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

2. Name of negative ion ends with ate

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 the following2
Name the following:
  • Name the following acids:
  • H2CO3 HClO3
  • HF HClO2
  • H2SO4 HClO
  • HBr HClO4
nonoxy acid
Nonoxy acid
  • Composed of H and other nonmetals other than oxygen that produce H+ in aqueous solution.
oxy acid
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
homework problems
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.
