Step method to draw lewis structure of C2F2

Step 1: Find valence e- for all atoms. Add them together.

C=4x2=8
F=7x2=14

Total=22

Step2: Find octet e- for each atom and add them together.

C=8x2=16   F=8x2=16

Total=32

Step3: Subtract step 1 total from step 2.  Gives you bonding e-.

32-22=10e-

Step 4: Find number of bonds by diving the number in step 3 by 2(because each bond is made of 2 e-)

10e-/2= 5 bond pairs

Step 5: Find the number of nonbonding (lone pairs) e-. Subtract step 3 number from step 1.

22-10= 12e-=6 lone pairs

Use information from step 4 and 5 to draw the lewis structure.

Lewis dot structure of C2F2

Alternatively a dot method can be used to draw the lewis structure of C2F2
Calculate the total valence electrons in the molecule.
C=4x2=8
F=7x2=14

Total=22


Put two canbon atoms in the center side by side.Put one fluorine on each carbon atom. Put the electrons and arrange them until all atoms get octet state.
