Which of the following is an example of vic-dihalide? - Toppr
Vicinal dihalides compounds that have halogen on adjacent carbons, are prepared by reaction between a halogen and an alkene. 1, 2- Dichloroethane leads all other organohalogen compounds in terms of its annual production which averages to 20 million tons per year.
Assertion (A): 1,2-dichloroethane is a vicinal dihalide.
Assertion (A): 1,2-dichloroethane is a vicinal dihalide. Reason (R): Two chlorine atoms present on adjacent carbon atoms is known as vicinal dihalide. Both Assertion and Reason are correct and Reason is the correct explanation to Assertion; Both Assertion and Reason are correct and Reason is not the correct explanation to Assertion
How many isomeric vicinal-dihalides are possible the compound …
In vicinal-dihalides, the two − C l atoms are present at adjacent positions. In case of C 3 H 6 C l 2 only one such structure is possible. Hence, only one vicinal-dihalides is possible for C 3 H 6 C l 2.
Vicinal dihalides undergo double dehydrohalogenation to give
When vicinal dibromide is heated with KOH in ethanol followed by sodamide (200 ∘ C), double dehydrohalogenation takes place giving alkyne. Which of the following fails to give alkyne according to this procedure?

allylic halide. Solution. Verified by Toppr. The correct option is B gem-dihalide. Ethylidene chloride is a gem-dihalide. Gem Dihalide is a compound that have two halogen atoms on the same carbon atom. The above is the structure of gem-dihalide. Was this answer helpful?
Write the chemical equation for the preparation of ethene from
(B) Alkynes are obtained from vicinal dihalides by dehydrohalogenation which is carried out in two steps: The first step is to prepare unsaturated halides. The halides formed have a halogen attached to a double bonded carbon. These halides are called vinylic halides which are not reactive in nature.
