MCQ
Among the following, the species having the smallest bond is
- A$NO^-$
- ✓$NO^+$
- C$O_2$
- D$NO$
✓
Answer
Correct option: B.
$NO^+$
b
$NO^-(16) - B.O. - 2\,\,\,\,\,\,\,\,\,\,O_2(16) - B.O. - 2$
$NO^+(14) - B.O. - 3\,\,\,\,\,\,\,\,\,\,NO(15) - B.O. -2.5$
Higher the bond order lower is the bond length . Hence $NO^+$ will have smallest bond.
$NO^-(16) - B.O. - 2\,\,\,\,\,\,\,\,\,\,O_2(16) - B.O. - 2$
$NO^+(14) - B.O. - 3\,\,\,\,\,\,\,\,\,\,NO(15) - B.O. -2.5$
Higher the bond order lower is the bond length . Hence $NO^+$ will have smallest bond.
