# What are the three possible Lewis structures for C_2H_2Cl_2?

May 14, 2018

Here's what I get.

#### Explanation:

The first isomer has two chlorine atoms on the same carbon,

The π-bond in alkenes prevents rotation about the $\text{C-C}$ axis.

Thus, thee are two isomers with the chlorine atoms on different carbons:

• one has the two chlorine atoms on the same side of the double bond
• the other has the two chlorine atoms on opposite sides of the double bond
