Copper (II) ions are able to participate in co-ordinate covalent bonding because they
- A. are coloured
- B. are positively charged
- C. have vacant d-orbital
- D. have unpaired electrons
Correct Answer: C. have vacant d-orbital
Explanation
Copper (II) ions have vacant d-orbitals. This means that they can accept a pair of electrons from a donor atom. When a copper (II) ion accepts a pair of electrons, it forms a co-ordinate covalent bond with the donor atom.
