If we do the hydrogenation/Ni on an alkene, it removes the double bond and adds two hydrogens, and if i have conjuagted diene with 1 mol of H2, does the mechanism change? because in the powerpoint presentation, the product has 1 double left (which makes sense) but it changes position.
for example 1,3 buta-diene + H2/Ni -> 2-Butene
Why does it change position? anyone have a link or book reference for this reaction
