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?

Answer: (D)

Bond order and bond length work against each other: the higher the bond order, the shorter and stronger the bond.

NO X^{+}

has a bond order of 3 while

NO

stands at 2.5, so

NO X^{+}

is pulled in tighter. That leaves the bond in neutral

NO

the longer of the two.
