Question

A student is completing the following reaction in lab.

1-hexene + Br2 ? 1,2-dibromohexane

1-Hexene has a molar mass of 84.1608 g/mol, bromine has a molar mass of 159.808 g/mol, and 1,2-dibromohexane has a molar mass of 243.97 g/mol.

Lucky for you the student has the mass of the reactants that was used. Determine the theoretical yield to three decimal places of 1,2-dibromohexane given the following masses. Be sure to check to see which reagent is the limiting reagent!

1-hexene used: 6.588 g

bromine used: 12.656 g

Explanation / Answer

theoretical yield is 19.0976602.

limiting reagent is 1-hexene. because bromine amount will be in excess so we wont take it as limiting reagent
