Q: What type of isomerism is exhibited by 1,2-dichloroethene?
Solution: 1,2-dichloroethene can exist as cis and trans isomers due to the restricted rotation around the double bond.
Steps: 5
Step 1: Understand what isomerism means. Isomerism is when two or more compounds have the same formula but different structures.
Step 2: Identify the structure of 1,2-dichloroethene. It has a double bond between two carbon atoms and two chlorine atoms attached to the first and second carbon.
Step 3: Recognize that the double bond in 1,2-dichloroethene prevents the carbon atoms from rotating freely.
Step 4: Learn about cis and trans isomers. Cis means that similar groups (like the chlorine atoms) are on the same side of the double bond, while trans means they are on opposite sides.
Step 5: Conclude that 1,2-dichloroethene can exist in two forms: one where the chlorines are on the same side (cis) and one where they are on opposite sides (trans).
