Slide 4 : Ritesh Kesharwani sir http://mona.250free.com Coordinate Chemistry Bonding in Coordinate Complex:-
“Worner’s Theory”
1. Primary and Secondary Valency
2. Satisfy Simultaneously
3. Primary = - ion but Secondary = +, -, Neutral ions
4. Primary = out of from bracket Secondary = under bracket
5. Directional effect due to secondary
6. M + L = Complex
