Question
Among the following groupings which represents the collection of isoelectronic species?
A.
$$N{O^ + },C_2^{2 - },O_2^ - ,CO$$
B.
$${N_2},C_2^{2 - },CO,NO$$
C.
$$CO,N{O^ + },C{N^ - },C_2^{2 - }$$
D.
$$NO,C{N^ - },{N_2},O_2^ - $$
Answer :
$$CO,N{O^ + },C{N^ - },C_2^{2 - }$$
Solution :
The species $$CO,N{O^ + },C{N^ - }$$ and $$C_2^{2 - }$$ contain
14 electrons each.
