Question

How many of these molecules are diamagnetic and have bond order more than 2 O22+, C O, barC N, N O, N O+, N2, O2+, N22-, O22- (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

O22+, C O, barC N, N O+, N2 have bond order 3 and are diamagnetic also. NO , O 2+have bond order 2.5 but are paramagnetic. N22-, O22- have bond order 2 and 1 respectively.

Q. How many of these molecules are diamagnetic and have bond order more than $2$
$O_{2}^{2 +}, CO, \overset{ˉ}{C} N, NO, N O^{+}, N_{2}, O_{2}^{+}, N_{2}^{2 -}, O_{2}^{2 -}$

$O_{2}^{2 +}, CO, \overset{ˉ}{C} N, N O^{+}, N_{2}$ have bond order $3$ and are diamagnetic also.
$NO, O_{2}^{+}$ have bond order $2.5$ but are paramagnetic.
$N_{2}^{2 -}, O_{2}^{2 -}$ have bond order $2$ and $1$ respectively.
