Question

Which of the following has smallest bond length?

• A. $O_2$
• B. $N_2$
• C. $C{l}_2$
• D. $HCl$

Answer 1

Answer: (B)

$N_2$

Let us consider the problem:

Let us consider the arranged bond energy in $kJmo{l}^{-1}$ would be:

$F_2\left(155\right)<N_2\left(965\right)<H_2\left(432\right)<O_2\left(494\right)$

Hence the correct answer is $O_2$.
