Reaction of ${[Co {(H_{2} O)}_{6}]}^{2 +}$ with excess ammonia and in the presence of oxygen results into a diamagnetic product. Number of electrons present in $t_{2 g}$ -orbitals of the product is

Answer:

6.00

Solution:

${[Co {(H_{2} O)}_{6}]}^{2 +} + 6 N H_{3} \overset{air}{\to} {[Co {({NH}_{3})}_{6}]}^{3 +} + 6 H_{2} O + e^{-}$

Electronic configuration of ${[Co {({NH}_{3})}_{6}]}^{3 +} = t_{2 g}^{6} e_{g}^{0}$

Air oxides the $Co$ (II) to $Co$ (III)
