Exam 1: Ionic and Molecular Nomenclature Flashcards
Ionic (binary) compounds
name of cation (metal) + base name of anion (nonmetal) + -ide
KCl –> potassium chlorIDE
CaO –> calcium oxIDE
Ionic (polyatomic) compounds
name of cation (metal) + name of polyatomic compound (functional groups)
Ionic (transition metal) compounds
- determine charge of cation from known charge of ion
- cation charge = [-(anion subscript)(anion charge)]/(cation subscript)
- indicate charge using roman numerals in parenthesis
Chromium (III) bromide
mono - (molecular)
one
di - (molecular)
two
tri - (molecular)
three
tetra - (molecular)
four
penta - (molecular)
five
hexa - (molecular)
six
hepta - (molecular)
seven
octa - (molecular)
eight
nona - (molecular)
nine
deca - (molecular)
ten
Molecular (binary) compounds
prefix + name of first element + prefix + base name of second element + -ide
- if first element is singular, no prefix
- cannot reduce the formula, yields a different substance
NO2 –> nitrogen DIoxIDE
N2O –> DInitrogen MONoxIDE
NI3 –> nitrogen TRIodIDE
Binary acids
hydro + base name of nonmetal + -ic + acid
- will start with H
- only 4
HCl –> HYDROchlorIC ACID
HBr –> HYDRObromIC ACID
HI –> HYDROiodIC ACID
HF –> HYDROfluorIC ACID
