    Study Notes

    Types of Amines

    • R1 denotes a primary amine, characterized by one alkyl/aryl group attached to a nitrogen atom.
    • R2 denotes a secondary amine, with two alkyl/aryl groups attached to nitrogen.
    • R3 denotes a tertiary amine, having three alkyl/aryl groups attached to nitrogen.

    Common Molecular Compounds

    • Sulfur dioxide is represented by the formula SO2.
    • Phosphorus trichloride is denoted as PCl3.
    • Carbon tetrabromide has the chemical formula CBr4.
    • Chlorine monofluoride is represented by ClF.

    Phosphine and Derivatives

    • Ph3 can be known commonly as phosphine or IUPAC as phosphorus trihydride.
    • Nitrogen triiodide corresponds to the formula NI3.
    • Hydrogen bromide represents both HBr as a compound and hydrobromic acid when dissolved in water.

    Acids and Their Formulas

    • Sulfuric acid corresponds to H2SO4.
    • Iron(III) hydroxide is represented by Fe(OH)3.

    • The IUPAC name for NO is nitric oxide.
    • Antimony trichloride is represented by SbCl3.
    • P2O5 is correctly named phosphorus pentoxide.
    • Hexaboron silicide should be corrected to B6Si; subscripts need adjusting.
    • SO3 is known as sulfur trioxide.
    • Phosphine is accurately represented by the formula PH3.
    • The compound formed by silicon and oxygen is called silicon dioxide.

    Molecular Formulas and Corrections

    • Copper(II) hydroxide should be corrected from Cu2OH to Cu(OH)2 to accurately represent the compound.
    • Nitrogen trihydride corresponds to NH3.
    • Carbon dioxide is an example of an IUPAC name for a covalent compound.
