Question

According to the postulates of Werner for coordination compounds

• A. primary valency is ionizable
• B. secondary valency is ionizable
• C. primary and secondary valencies are non-ionizable
• D. only primary valency is non-ionizable

Answer 1

The correct option is A primary valency is ionizable

Primary valency	Secondary valency
It is denoted by dotted/dashed line	It is denoted by solid line
It is equal to oxidation number of central atom	It is equal to coordination number
It is non-directional	It is directional in nature
It is ionisable	It is non ionisable
