Question

Which of the following are isoelectronic molecules?

$NO^+$ and $F_2$

$CO$ and $O_2^{2-}$

$CO$ and $NO^+$

$O_2^{2-}$ and $N_2$

Answer

$CO$ and $NO^+$

Explanation

Solution

Number of electrons in $CO = 6 + 8 = 14$ electrons.
Number of electrons in $NO^+ = 7 + 8 - 1 = 14$ electrons.
$\therefore CO$ and $NO^+$ are isoelectronic spedes.
