Missing parts
  1. Answer
    ionisable (ionic)
    Choices
    1. ionisable (ionic)
    2. covalent
    3. metallic
  2. Answer
    non-ionisable (covalent)
    Choices
    1. non-ionisable (covalent)
    2. ionic
    3. hydrogen
Complete the statement
Werner proposed two kinds of linkage. The primary linkage corresponds to the {0} bond, and the secondary linkage to the {1} bond.
Werner's two linkages map onto modern bonding language. Source: syllabus Chemistry Part I, Ch 5 Coordination Compounds.

    3. Oxalate is a unidentate ligand
  2. False statement
    Coordination number equals the number of ligands
    Statements
    1. Coordination number equals the number of ligands
    2. Coordination number counts sigma bonds only
    3. Pi bonds are not counted
  3. False statement

    Statements
    1. The coordination sphere sits inside square brackets
    2. Counter ions are part of the coordination sphere
    3. Counter ions are written outside the brackets
