A
Cu⁺

B
Ag⁺

C
Ni²⁺

D
Fe²⁺

Question 3
1 / -0

According to Lewis the ligands are

A
Acidic in nature

B
Basic in nature

C
Neither acidic nor basic

D
Some are acidic and others are basic

Solution

According to Lewis the ligands are basic in nature.
Question 4
1 / -0

The coordination number of a central metal atom in a complex is determined by

A
The number of ligands around a metal ion bonded by sigma and pi-bonds both.

B
The number around a metal ion bonded by pi-bonds

C
The number of ligands around a metal ion bonded by sigma bonds
