Question
Consider the following statements:
According the Werner′s theory.
(1) Ligands are connected to the metal ions by ionic bonds.
(2) Secondary valencies have directional properties
(3) Secondary valencies are non-ionisable
Of these statements:
According the Werner′s theory.
(1) Ligands are connected to the metal ions by ionic bonds.
(2) Secondary valencies have directional properties
(3) Secondary valencies are non-ionisable
Of these statements:
Options
A.1, 2 and 3 are correct
B.2 and 3 are correct
C.1 and 3 are correct
D.1 and 2 are correct
Solution
According to Werner′s theory statements (2) and (3) are correct.
(1) Ligands are connected to the metal ion by coordinate covalent bond (dative bond).
(2) Secondary valencies i.e. coordination number give rise to stereochemistry of the complexes because of their directional properties.
(3) Secondary valencies correspond to coordination number i.e. number of s-bonds between metal ion and lignds.
