Step 1: Carbon (EN = 2.55) is less electronegative than chlorine (EN = 3.16) so carbon is the central atom.
Step 2: The total number of valence electrons present in C2Cl4 is:
Group Valence Electrons
C 4A 2 × 4 e– = 8 e–
Cl 7A 4 × 7 e– = 28 e–
Total: 36 valence e–
Step 3: Let’s first connect each atom with a single bond:
Construct a Lewis structure for each molecule: C2Cl4
