Question

If the general formula of a metal carbonyl is $M{(CO)}_x.$ (where M = metal, $x=4$ ) then metal is bonded with

• A. $C\equiv O$ triple bond
• B. carbon and oxygen
• C. carbon
• D. oxygen

Answer 1

Answer: (C)

The general formula of metal carbonyl is $M{(CO)}_x$ where M = metal and $x=4$ Hence, formula of metal carbonyl $=M{(CO)}_4$ $CO-\underset{\begin{array}{c}|\\ CO\end{array}}{\stackrel{\begin{array}{c}CO\\ |\end{array}}{M}}-CO$
Therefore, metal atom will be bonded by carbon atom of carbonyl directly.
