Question

In $[Co(NH_3)_6]CI_3$, the number of covalent bonds is

• A. 3
• B. 6
• C. 9
• D. 18

Answer 1

Answer: (D)

18

Answer 2

$M - L$ bond is coordinate. In ligand itself, $NH_{3}$, three hydrogens are covalently linked to nitrogen atoms. Hence, total number of covalent bonds$= 6 \times 3 = 18$
