Alkynes can be prepared by two sequential E1 dehydrohalogenations.Select answer from the options belowTrueFalse

The statement is True.

Explanation:

1. Alkynes Formation: Alkynes can indeed be formed through two sequential E1 dehydrohalogenation reactions. In this process, a vicinal dihalide (a compound with two halogen atoms on adjacent carbon atoms) can undergo elimination reactions to ultimately yield an alkyne.

2. E1 Mechanism: The E1 mechanism involves two steps:

   • First, the leaving group departs, forming a carbocation.
   • Second, a base removes a proton, leading to the formation of a double bond in the first elimination, and subsequently, the second elimination can lead to the formation of a triple bond characteristic of alkynes.

Therefore, the correct response to the statement is True.
