Q. According to postulates of Werner’s theory for coordination compounds, which of the following is true?
A) Primary valencies are ionizable
B) Secondary valencies are ionizable
C) Only primary valencies are non-ionizable
D) Primary and secondary valencies are non-ionizable
Explanation
(a)
According to postulates of Werner’s theory for coordination compounds, metal atoms exhibit two types of valencies i.e., primary valency and secondary valency. The primary valency is ionisable whereas the secondary valency is non-ionisable.
