What is the Difference Between Ethylene Dichloride and Ethylidene Chloride?

Ethylene dichloride and ethylidene chloride are two different organic compounds that are isomers, meaning they have the same molecular formula but different structures. The key difference between the two is the position of the chlorine atoms on the carbon backbone.

• Ethylene dichloride: Also known as 1,2-dichloroethane, ethylene dichloride has two chlorine atoms bound to two different carbon atoms. It is used in various applications, such as vinyl chloride monomer production, as a degreaser, paint remover, source of chlorine for laboratory uses, in dry cleaning, and as an anti-knock additive in leaded fuels.
• Ethylidene chloride: Also called 1,1-dichloroethane, ethylidene chloride contains two chlorine atoms bound to the same carbon atom. It is mainly used as feedstock for chemical synthesis, particularly for the synthesis of 1,1,1-trichloroethane.

These two compounds can be differentiated by reacting with water. Ethylidene chloride forms acetaldehyde when reacted with water, while ethylene dichloride forms 2-chloroethanol.

Comparative Table: Ethylene Dichloride vs Ethylidene Chloride

Ethylene dichloride and ethylidene chloride are two organic compounds with an ethylene chemical structure where two chlorine atoms replace hydrogen atoms. They have different properties and applications, as summarized in the table below:

Ethylene dichloride, also known as 1,2-dichloroethane, is a clear liquid with a molecular formula of C2H2Cl2. It is water-soluble and has a variety of industrial applications. Ethylidene chloride, also known as 1,1-dichloroethane, is a colorless and oily liquid with a molecular formula of C2HCl3. It is not easily soluble in water but is miscible with many organic solvents. It is primarily used as an intermediate in the synthesis of other chemicals.
