Question

Draw a Lewis structure for each of the following:

1. N₂H₄
2. CO₃^2-
3. N₂H₂
4. CO₂
5. HOCl

Short answer

a. N₂H₂

=10+4=14

b. CO₃^2-

=4+18+2=24

c. N₂H₂

=10+2=12

d. C0₂

=4+12=16

e. HOCl

=1+6+7+14

Step-by-step solution

Determine the total number of valence electrons.

a. N₂H₂

=10+4=14

b. CO₃^2-

=4+18+2=24

c. N₂H₂

=10+2=12

d. C0₂

=4+12=16

e. HOCl

=1+6+7+14

Distribute the atoms, form bonds and fill in their octets

Use the number of valence electrons determined in step1 to fill up the octet.

a. N₂H₄

Bonded electrons =10

Lone pair of electrons=2

b. CO₃^2-

Bonded electrons=8

Lone pair of electrons =8

c. N₂H₂

Bonded electrons=8

Lone pair of electrons=2

d. CO₂

Bonded electrons =8

Lone pair of electrons =4

e. HOCl

Bonded electrons =4

Lone pair of electrons= 5
