medium
$O_2^+ ; O_2 , O_2^-$ અને $O_2^{2-}$ માટે $O -O$ બંધમાં આંતરકેન્દ્રિય અંતર અનુક્રમે જણાવો.
A
$1.30\mathop {\,A}\limits^o ,1.49\,\mathop A\limits^o ,1.12\,\mathop A\limits^o ,1.21\,\mathop A\limits^o $
B
$1.49\mathop {\,A}\limits^o ,1.21\,\mathop A\limits^o ,1.12\,\mathop A\limits^o ,1.30\,\mathop A\limits^o $
C
$1.21\mathop {\,A}\limits^o ,1.12\,\mathop A\limits^o ,1.49\,\mathop A\limits^o ,1.30\,\mathop A\limits^o $
D
$1.12\mathop {\,A}\limits^o ,1.21\,\mathop A\limits^o ,1.30\,\mathop A\limits^o ,1.49\,\mathop A\limits^o $
(JEE MAIN-2013)
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\mathop {\,A}\limits^o ,1.21\,\mathop A\limits^o ,1.30\,\mathop A\limits^o ,1.49\,\mathop A\limits^o $
