Chemical Bonding and Molecular Structure - Result Question 120
####124. $N_2$ and $O_2$ are converted into monoanions, $N_2{ }^{-}$ and $O_2^{-}$respectively. Which of the following statements is wrong?
[1997]
(a) In $N_2$, the $N-N$ bond weakens
(b) In $O_2$, the $O-O$ bond order increases
(c) In $O_2$, bond length decreases
(d) $N_2{ }^{-}$becomes diamagnetic
Show Answer
Solution:
- (b) We know that in $O_2$ bond, the order is 2 and in $O_2^{-}$bond, the order is 1.5. Therefore, the wrong statements is (b).
