Chemical Bonding and Molecular Structure - Result Question 101
####103. The pair of species that has the same bond order in the following is:
[NEET Kar: 2013]
(a) $O_2, B_2$
(b) $CO, NO^{+}$
(c) $NO^{-}, CN^{-}$
(d) $O_2, N_2$
Show Answer
Solution:
- (b) No. of electrons in $CO=6+8=14$
No. of electrons in $NO^{+}=7+8-1=14$
$\therefore CO$ and $NO^{+}$are isoelectronic species.
Isoelectronic species have identical bond order.
