Werner's theory was the first successful theory, which explained the properties of complexes. According to Werner's theory the primary and secondary valence of [Co(Cl3(NH3)3]Cl3 is :(a) 3 & 3 respectively (b) 6 & 6 respectively(c) 3 & 6 respectively (d) 6 & 3 respectively |

Answer» Correct Option (c) 3 & 6 respectively Explanation : According to Werner's theory primary valence means oxidation state and secondary valance means coordination number. Let oxidation state of Co in [CoCl3(NH3)3Cl3 is x x – 3 + 0 = + 3 x = 0 Primary valence = 3 Secondary valence = coordination numbers = 6 |
