The magnetic moment of\[[Co{{(N{{H}_{3}})}_{6}}]C{{l}_{3}}\]is
A) 1.73
B) 2.83
C) 6.6
D) zero
Correct Answer:
D
Solution :
In\[{{[Co{{(N{{H}_{3}})}_{6}}]}^{3+}}\]the oxidation state of\[Co\]is +3. \[{{[Co{{(N{{H}_{3}})}_{6}}]}^{3+}}\]does not contain unpaired electron hence, its magnetic moment is zero.
