Vedclass · Answer

(D) Isoelectronic species are those that have the same number of electrons.$(a) N_2 (7+7=14)$ and $CO (6+8=14)$. Both have $14$ electrons.$(b) CO_2 (6+8+8=22)$ and $N_2O (7+7+8=22)$. Both have $22$ electrons.$(c) CaO (20+8=28)$ and $MgS (12+16=28)$. Both have $28$ electrons.$(d) C_6H_6 (6 	imes 6 + 6 = 42)$ and $B_3N_3H_6 (3 	imes 5 + 3 	imes 7 + 6 = 15+21+6 = 42)$. Both have $42$ electrons.Since all pairs are isoelectronic,the correct option is $(d)$.
