We’re being asked to draw the 3 Lewis structures for C2H2Cl2 and indicate whether each is non-polar or polar. To do so, we first need to do the following steps:

Step 1: Determine the central atom in this molecule.

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis structure for the molecule.

Step 4: Draw dipole arrows for each bond.

Step 5: Determine the polarity of the molecule.


Step 1: Carbon (EN = 2.5) is less electronegative than chlorine (EN = 3) and hydrogen can only make 1 bond so carbon is the central atom. The two carbon atoms will be bonded to each other.
