Question

Statement 1 : Bond order for $C{O}^{+}$ is more than bond order in $CO$ whereas bond order in $N_2^{+}$ is less than $N_2$ whereas both are isoelectronics.
Statement 2 : Both have same bond order

• A. If both Statement $1$ and Statement $2$ are true and the statement $2$ is the correct explanation of the statement $1$
• B. If both Statement $1$ and Statement $2$ are true but statement $2$ is not the correct explanation of the statement $1$
• C. If Statement $1$ is true but Statement $2$ is false
• D. If Statement $1$ is false but Statement $2$ is true

Answer 1

Answer: (C)

Both $N_2$ and $CO$ have different $MO$ configuration but bond order is same which results a change in $N_2^{+}$ and $C{O}^{+}$ configuration and thus, bond order of $N_2^{+}$ and $C{O}^{+}$ are different.
