Answer: a. 6 (3x2=6)

B. 4 (4x1=4)

C. 6 (4 (1) + 2 (1) = 4+2=6

D. 4

E. 6 (3 (2) = 6)

F. 4 (2 (1) + 2 (1) [2+2=4)

G. 5 (5 (1) = 5)

H. 4 (2 (1) + 2 (1) = 2+2=4)

Explanation:

Coordination number = no of ligands

= No of ligands X denticity

Denticity is nothing but type of ligands like mono, do and tetradentate ligands.
