Draw the product(s) that would be produced from the treatment of the following alkyne with HCl (2 equiv.).
Determine the alkyne and any other reactant that are needed to produce the given molecule.
Draw a mechanism for the reaction of 1 mol of 1-propyne with 2 moles of HBr. The mechanism should explain the Markovnikov regioselectivity of the reaction.
Write products for the following alkyne hydrohalogenation reactions:
a. ethynylcyclohexane + 2 HClb. cyclooctyne + 2 HBr
Predict the alkyne and reactants needed to produce the following haloalkene.
Draw the product of the addition of one equivalent of the reagent to the molecule shown below.
The addition reaction of HX to internal alkynes is anti addition as shown below:
Two chemistry students have a conflicting assessment on whether or not anti-addition would occur on terminal alkynes. Propose a mechanism that could help settle this disagreement.
