Chemical Bonding And Molecular Structure Question 444
Question: The correct order of bond dissociation energy among $ N_2,,O_2,O_2^{-} $ is shown in which of the following arrangements-
Options:
A) $ N_2>O_2^{-}>O_2 $
B) $ O_2^{-}>O_2>N_2 $
C) $ N_2>O_2>O_2^{-} $
D) $ O_2>O_2^{-}>N_2 $
Show Answer
Answer:
Correct Answer: C
Solution:
- The bond order of $ N_2\text{, }O_2, $ and $ O_2^{-} $ are respectively 3, 2 and 1.5 Since higher bond order implies higher bond dissociation energy hence the correct order will be $ N_3>O_2>O_2^{-} $
