Question

Statement 1 : Bond order for $CO^+$ 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 $CO^+$ configuration and thus, bond order of $N^+_2$ and $CO^+$ are different.
