Reactions of Alkynes
In this problem we shall consider three alkyne reactants:
ethyne (acetylene)     1-butyne     2-butyne    

These compounds may be reacted with nine different reagents:
Hydrogen & Lindlar catalyst Hydrogen & Pt catalyst H3O(+) & HgSO4
Hydrogen Chloride
(1 equivalent)
Sodium in liq. Ammonia Bromine
(2 equivalents)
(i) Disiamylborane, R2BH
(ii) H2O2 in NaOH soln.
Hydrogen Chloride
(2 equivalents)
(i) Sodium Amide (1 equivalent)
(ii) Ethyl bromide

Select one alkyne from the first group, and one reagent from the second group.
