Question

The bond order in NO is 2.5 while that in $NO^+$ is 3. Which of the following statements is true for these two species ?

• A. Bond length in $NO^+$ is greater than in NO
• B. Bond length is unpredictable
• C. Bond length in $NO^+$ is equal to that in NO
• D. Bond length in NO is greater than in $NO^+$

Answer 1

Answer: (D)

Bond length in NO is greater than in $NO^+$

Answer 2

B.O. in NO is 2.5 while that NO+ is 3. As B.O. is inversely proportional to bond length, bond length in NO is more than in $NO^+$
