Question

co2 is isoelectronic with

Answer 1

Isoelectronic species are those which has same no of electrons.

CO2 has 6+(2×8)=22e

NO2+ is isoelectronic with CO2

Because it has 7+ 2×8. -1=22 e

Answer 2

How many electrons do CO2 have?

-> let's find out!

Electrons of C= 6 and of O = 8 but there

are 2 Oxygen atoms so it = 16

Total becomes 22.

-> now some basic oxide as ex or option

a)N2O2 have 30 electrons

b)NO have 15 electrons

c)N2O have 22 electrons

d)NO2 have 23 electrons

Hence option c) N2O is the correct answer.

as there electron are same

Hope it helps.
