Question

Which of the following molecules have the maximum number of electrons ?

1)hcl
2)nh3
3)no
4)co2​

Answer 1

Explanation:

Number of electrons in methane =6(carbon) + 1 x 4(hydrogen) =10.

Number of electrons in carbon dioxide =6(carbon) + 8 x 2(oxygen) =22.

Number of electrons in nitrogen dioxide =7(nitrogen) + 8 x 2(oxygen) =23.

Number of electrons in nitrous oxide =7 x 2(nitrogen) + 8(oxygen) =22.

So, NO

2

contains the maximum number of electrons.
