Options:
A) $ 1.30\overset{o}{\mathop{A}},,1.49\overset{o}{\mathop{A}},,1.12\overset{o}{\mathop{A}},,1.21\overset{o}{\mathop{A}}, $
B) $ 1.49\overset{o}{\mathop{A}},,1.21\overset{o}{\mathop{A}},,1.12\overset{o}{\mathop{A}},,,1.30\overset{o}{\mathop{A}}, $
C) $ 1.21\overset{o}{\mathop{A}},,1.12\overset{o}{\mathop{A}},,1.49\overset{o}{\mathop{A}},,1.30\overset{o}{\mathop{A}}, $
D) $ 1.12\overset{o}{\mathop{A}},,1.21\overset{o}{\mathop{A}},,1.30\overset{o}{\mathop{A}},,1.49\overset{o}{\mathop{A}}, $
Show Answer
Answer:
Correct Answer: D
Solution:
- The bond length follows the order $ O_2^{+}<O_2<O_2^{-}<O_2^{2-}~ $ According to this the possible values are $ 1.12\overset{o}{\mathop{A}}1.21\overset{o}{\mathop{A}}1.30\overset{o}{\mathop{A}}1.49\overset{o}{\mathop{A}}, $
