MCQ
Which one of the following constitutes a group of the isoelectronic species?
- A$C_2^{2-} ,O_2^-,CO,NO$
- ✓$NO^+,C_2^{2-},CN^-,N_2$
- C$CN^- , N_2 , O_2^{2-} ,C_2^{2-}$
- D$N_2, O_2^- ,NO^+,CO$
✓
Answer
Correct option: B.
$NO^+,C_2^{2-},CN^-,N_2$
b
Isoelectronic species possess same number of electrons. $NO ^{+}, C _2^{2-}, CN ^{-}$ and $N _2$ , each have $14$ electrons and thus are isoelectronic.
