Question
The bond order in $$NO\,\,{\text{is}}\,\,2.5$$ while that in $$N{O^ + }\,\,{\text{is}}\,\,3$$ . Which of the following statements is true for these two species ?
A.
Bond length in $$N{O^ + }\,\,{\text{is}}$$ equal to that in $$NO$$
B.
Bond length in $$NO\,$$ is greater than in $$N{O^ + }$$
C.
Bond length in $$N{O^ + }$$ is greater than in $$\,NO\,$$
D.
Bond length is unpredictable
Answer :
Bond length in $$NO\,$$ is greater than in $$N{O^ + }$$
Solution :
Now since bond order of $$N{O^ + }\,$$ given (3) is higher than that of $$\,NO$$ $$(\,2.5\,)$$ . Thus bond length of $$N{O^ + }$$ will be shorter.
