Solution

The best reagent to convert 1-hexyne into (E)-1-bromo-1-hexene is 1 equiv HBr.

Here's the step-by-step process:

  1. 1-hexyne is an alkyne, which means it has a triple bond between two of the carbon atoms.

  2. When 1 equiv HBr is added to 1-hexyne, it will add across the triple bond in a Markovnikov manner. This means that the bromine (Br) will attach to the carbon atom that has the most hydrogen atoms attached to it already.

  3. The result of this reaction is (E)-1-bromo-1-hexene, which is an alkene with a bromine atom attached to one of the carbon atoms.

The other reagents listed (1 equiv. Br2, CCl4, xs HBr, xs Br2, CCl4, 1 equiv HBr, ROOR) would either add too many bromine atoms or add them in the wrong place. Therefore, 1 equiv HBr is the best reagent for this reaction.
