Arrange the following molecules in decreasing bond length.
A. O2 > O2– > O2+ > O2 2-
B. O2 2- > O2 – > O2 > O2 +
C. O2 2- > O2 – > O2 + > O2
D. O2 – > O2 + > O2 2- > O2
Answer:B
Arrange the following molecules in decreasing bond length.
A. O2 > O2– > O2+ > O2 2- B. O2 2- > O2 – > O2 > O2 + C. O2 2- > O2 – > O2 + > O2 D. O2 – > O2 + > O2 2- > O2
Explanation: The bond length is inversely proportional to the bond order. Therefore, the correct is: O2 2- > O2 – > O2 > O2 +.
