What are the three possible Lewis structures for #C_2H_2Cl_2#?
Here's what I get.
The first isomer has two chlorine atoms on the same carbon,
The π-bond in alkenes prevents rotation about the
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
