According to crystal field theory, the ( M ) - Lbond in a complex is

Options

  1. Apurely ionio
  2. Bpurely covalent
  3. Cpurely co-ordinate
  4. Dpartially covalent

Correct answer

A. purely ionio

Step-by-step solution

The assumption of CFT is that ( M ) - ( L ) interactions are purely electrostatic in nature. In an octahedral metal complex electrostatic interaction of a positively charged metal ion with six negatively charged ligands or with the negative ends of dipoles associated with the six ligands can be seen.
