Ethylene dichloride and ethylydene dichloride areisomeric compounds. Identify the statement which is not applicable to both of them

react with aqueous potash and give the same product

The answer is (2) react with aqueous potash and give the same product.

Ethylene dichloride (1,2-dichloroethane) and ethylidene dichloride (1,1-dichloroethane) are both dihalides, but they have different structures. Ethylene dichloride has two chlorine atoms on adjacent carbon atoms, while ethylidene dichloride has two chlorine atoms on the same carbon atom.

Aqueous potash (KOH) is a strong base, and it can react with both ethylene dichloride and ethylidene dichloride. However, the products of the reaction are different. Ethylene dichloride reacts with aqueous potash to form ethylene glycol, while ethylidene dichloride reacts with aqueous potash to form acetaldehyde.

Therefore, statement (2) is not applicable to both ethylene dichloride and ethylidene dichloride.

The other statements are applicable to both ethylene dichloride and ethylidene dichloride. Both compounds react with alcoholic potash to form ethyl alcohol, and both compounds give Beilstein's test.

Beilstein's test is a chemical test that is used to detect the presence of halogens in a compound. The test involves heating the compound in a flame, and if the compound contains halogens, a green flame will be produced.
