Vedclass · Answer

(A) According to Werner's theory of coordination compounds:$(1)$ The central metal atom is linked to ligands by coordinate bonds,which are also known as dative bonds. This statement is correct.$(2)$ Secondary valencies correspond to the coordination number and are directed in space around the central metal ion,giving the complex a specific geometry. Thus,they have directional properties. This statement is correct.$(3)$ Secondary valencies are non-ionisable because they are directly attached to the metal ion within the coordination sphere. This statement is correct.Since all three statements $(1, 2, 3)$ are correct,the correct option is $A$.
