To determine the reaction between 1-pentyne and 2 molar HBr, we need to first understand the nature of the reactants and the conditions under which the reaction takes place.

1-pentyne is an alkyne with a molecular formula C₅H₈, and HBr is hydrobromic acid. In this case, the HBr is present in a concentration of 2 molar, which means there are 2 moles of HBr per liter of solution.

The reaction between 1-pentyne and HBr is an addition reaction. Alkynes, like 1-pentyne, readily undergo addition reactions where the triple bond (C≡C) is broken and new bonds are formed.
