Question

Ligands are neutral or ionic species capable of donating at least one electron pair to central metal. Hence ligands can be of different denticities.

$\left[Mn{\left(CO\right)}_5\right]$ can attain more stability by :

• A. Oxidation of itself
• B. Reduction of itself
• C. Dimerization
• D. Both ( B ) and ( C )

Answer 1

The correct option is D Both ( B ) and ( C )

EAN value of $\left[Mn\right(CO{)}_5]$ is $25+20=35$ which is not equal to 36.

So it can attain EAN value of 36 by dimerization and by reduction.

So it can attain stability by reduction & dimerization.
