Q27 / 90 · JEE Main 2022 (24 Jun Shift 1) · Chemistry

In the cobalt-carbonyl complex : $[{Co}_{2} {(CO)}_{8}]$ , number of $Co - Co$ bonds is " $X$ " and terminal $CO$ ligands is " $Y$ ". $X + Y =$ ___

Correct answer: 7

Solution

The number of $Co - Co$ bonds are $1$ and the number of $Co - CO$ terminal bonds are $6$ . Hence, $x + y = 7$ .

Hence, the correct answer is 7.
