Consider the 1,2-Dichloro Derivative of Ethylene, in Which One of the Hydrogen

Consider the 1,2-dichloro derivative of ethylene, in which one of the hydrogen atoms on each of the carbon atoms in ethylene is substituted with a chlorine atom, giving the structural formula CHClCHCl. Does this molecule have geometrical isomers? Remember that ethylene does not.

A) Yes, because the chlorines can be placed on the same or opposite sides of the double bond.
B) Yes, because the chlorines can be placed on either one or both of the carbons.
C) No, because both the formula and bonds are the same in all skeletal structures.
D) No, because the two structures can interconvert through bond rotation.
E) No, because there are less than four atoms bound to each carbon.
