    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

    Correct Answer: C

    Solution :

     The general formula of metal carbonyl is \[M{{(CO)}_{x}}\] where   M = metal and \[x=4\] Hence, formula of metal carbonyl\[=M{{(CO)}_{4}}\] \[CO-\underset{\begin{smallmatrix}  | \\  CO \end{smallmatrix}}{\overset{\begin{smallmatrix}  CO \\  | \end{smallmatrix}}{\mathop{M}}}\,-CO\] Therefore, metal atom will be bonded by carbon atom of carbonyl directly.
