Alkynes can be prepared by two sequential E2 dehydrohalogenations.Select answer from the options belowTrueFalse

Assessing the Statement

1. Understanding E2 Mechanism: The E2 (bimolecular elimination) mechanism involves the removal of a proton and a leaving group (usually a halogen).
2. Sequential Dehydrohalogenations: For an alkyne to form from a dihalide, two rounds of dehydrohalogenation are indeed required. This means that first a bromine (or another halogen) is removed along with a hydrogen from an adjacent carbon, resulting in an alkene. A second elimination then occurs to convert the alkene into an alkyne.

Conclusion

Given that alkynes can be synthesized through two E2 dehydrohalogenations of vicinal or geminal dihalides, the statement is True. Therefore, the correct answer is True.
