compound names and formulas
Compound Names and Formulas
  • Binary Ionic Compounds
  • Binary Molecular Compounds
  • Polyatomic Ionic Compounds
  • Organic Hydrocarbons
  • Acids
binary ionic compounds
BinaryIonic Compounds
  • Compounds composed of a metal cation and a nonmetal anion
  • First name is the name of the metal
  • Second name is the name of the nonmetal with an ide suffix
  • Ex. NaCl is sodium chloride
molecular binary compounds
Molecular Binary compounds
  • Composed of two elements both of which are nonmetals.
  • No ions present
  • First name is name of the first element with prefix
  • Second name is name of second element with prefix
  • Prefix indicates subscript number: mono, di, tri, tetra, penta, hexa, hepta, octa, nona and deca
  • Ex: Carbon monoxide – CO2
polyatomic ionic compounds
Polyatomic Ionic Compounds
  • Composed of metal cation and anion made up of two or more nonmetal atoms with a net negative charge
  • First name is name of metal cation
  • Second name is name of polyatomic anion
  • Ex. Sodium sulfate – Na2SO4
organic compounds
Organic Compounds
  • Hydrocarbons are made up of carbon and hydrogen atoms
  • Alkanes have the formula: CnH2n+2
  • Prefix defines the n value: n=1-9 meth, eth, pro, but, pent, hex, hept, oct, non, and dec
  • Name ends with ane suffix
  • Ex: methane – CH4
binary acids
Binary Acids
  • All acids contain hydrogen ion: H+
  • In binary acids the anions is a monoatomic nonmetal anion
  • Generic formula: HA
  • Prefix: hydro Suffix: ic
  • Ex. Hydrochloric acid - HCl
polyatomic acids
Polyatomic Acids
  • All acids contain hydrogen ion: H+
  • In polyatomic acids the anion is a polyatomic anion
  • Generic formula: HA
  • Prefix: none(unless polyatomic anion name has one) Suffix: ic(ate) or ous(ite)
  • Ex. chloric acid – HClO3
  • Ex: hypochlorous acid – HClO
writing formula for ionic compounds from formula
Writing formula for ionic compounds from formula
  • MxAy will be MyAx
  • Example: Calcium(2+) nitrate(1-) – Ca(NO3)2
  • Ammonium(1+) carbonate (2-) – (NH4)2CO3
writing molecular formula from name for binary molecular formulas
Writing Molecular formula from name for binary molecular formulas
  • Prefix indicates subscripts for that element
  • Dinitrogen pentoxide: N2O5
writing alkane formula from name
Writing Alkane formula from name
  • Prefix indicates carbon subscript, H subscript is 2n+2
  • Ethane: C2H6
writing acid formula from name
Writing Acid Formula from Name
  • First determine if it is binary, it will have a hydro prefix and ic suffix
  • All acid formulas begin with hydrogen ion
  • Treat them like an ionic binary compound
  • Determine anion element and charge
  • Ex: hydrosulfuric acid – H2S
polyatomic acids12
Polyatomic acids
  • Determine the anion and its charge
  • Treat it like a polyatomic ionic compound
  • Ex: nitric acid – HNO3
  • Ex: phosphoric acid – H3PO4
