Q. Which of the following is isoelectronic with$\ CO_{2}$?
A) $NO_{2}$
B) NO
C) $N_{2}O$
D) $N_{2}O_{4}$
Explanation
(c)
Isoelectronic species are those species which have equal number of electrons. Hence, $CO_{2}$ is isoelectronic with $N_{2}O.$
Number of electron in $CO_{2}\$=22
Number of electron in $N_{2}O\$=22
