નીચેના પૈકી શામાં અયુગ્મિત ઇલેક્ટ્રોન છે ?
A
$N_2$
B
$O_2^ - $
C
$N_2^{2 + }$
D
$O_2^{2 - }$
(JEE MAIN-2014)
Solution
$O_2^ – (17) = KK{(\sigma 2s)^2}({\sigma ^*}2{s^2}){(\sigma 2{p_x})^2}$
${(\pi 2{p_y})^2}{(\pi 2{p_z})^2}{({\pi ^*}2{p_y})^2}{({\pi ^*}2{p_z})^1}$
one unpaired electron – Paramagnetic
