Show the product or products for the following reactlons H3​C−C≡C−CH2​CH3​Pd/CH2​​=CH3​CH2​CH2​CH2​CH3​
H−C≡C⟶CH3​CH2​Cl2​2 equiv, Cl2​​→ HC≡CHCH⋅Br=​HC=C−CH3​ H−C≡C−CH3​CH3​CH2​Br=​CH3​CH2​−C≡C−CH3​ H−C≡C−CH2​CH2​CH3​CH3​Br−NaNH2​​−H3​C−C≡C−CH2​CH2​CH3​
Tell me the reagents you would use to make the product shown. Requires more than 1 reaction. H=C≡C−CH3​CH2​BrXaNH2​​= H3​C−C≡C−CH3​
