It was the first thory that could adequately account for the formation of complex compounds from valence saturated simple molecules.
His main proposals and possessions of this theory are;
1) Majority of elements display two types of valencies i.e a) Main valence which is ionisable and corresponds to the oxidation state.
b)Secondary valence which is non-ionisable and corresponds to coordination number.
2)He states that every element tends to possess both the main and secondary valencies.
3)Secondary valence is directed to exactly fixed postions in space
