MCQ
In which of the following processes, the bond order increases and paramagnetic character changes to diamagnetic one?
- A$O _2 \rightarrow O _2^{2-}$
- ✓$NO \rightarrow NO ^{+}$
- C$N _2 \rightarrow N _2^{+}$
- D$O _2 \rightarrow O _2^{+}$
✓
Answer
Correct option: B.
$NO \rightarrow NO ^{+}$
b
$NO$ is paramagnetic with $BO =2.5, NO ^{+}$is diamagnetic with $BO =3$
$NO$ is paramagnetic with $BO =2.5, NO ^{+}$is diamagnetic with $BO =3$
