Which of the following has the least conductivity in an aqueous solution:
Correct answer: B. Co(NH3)3Cl3
- A. Co(NH3)4Cl3
- B. Co(NH3)3Cl3
- C. Co(NH3)5Cl3
- D. Co(NH3)6Cl3
Explanation
Werner's theory.[Co(NH3)3Cl3] is non electrolyte. statement of theory: Negative ions satisfy the primary valances, which are generally ionisable. Secondary valences cannot be ionised. Neutral molecules or negative ions satisfy these needs. For a metal, the secondary valence is equal to the coordination number and is constant.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
