Question

For the given reaction :


Which of the following correctly represents (A) and (B)?

• A. (A) is $Zn/Zndust$ , and (B) is 1-bromopropane.
• B. (A) is $Zn/Zndust$ , and (B) is propene.
• C. (A) is $ZnO$ , and (B) is 1-bromopropane.
• D. (A) is $ZnO$ , and (B) is propyne.

Answer 1

The correct option is B (A) is $Zn/Zndust$ , and (B) is propene.

Vicinal Dihalides:Dihalides in which two halogen atoms are attached to two adjacent carbon atoms are known as vicinal dihalides.
Geminal Dihalides: Dihalides in which two halogen atoms are attached to same carbon atom are known as geminal dihalides.

Dehalogenation of Vicinal Dihalides:
Vicinal dihalides are reduced in presence of $Zn/Zndust$ to form alkenes.
The reaction is :
