(c) [Co (NH3) 4Br2]2 (SO4) 3

(d) [Pt (NH3) 4][PtCl4]

(e) [Cr (en) 3] (NO3) 3

(f) [Pd (NH3) 2Br2] (square planar)

    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.
