How is this the answer? I thought Wilkinson's catalyst turned all pi bonds into sigma bonds. Thanks!

Hey, Jaclyn!

That's actually not Wilkinson's catalyst! Remember that Wilkinson's catalyst generally is written as either the name or as RhCl(PPh3)3. That's a nickel boride catalyst, and there are two types. There is P-1, which generally fully reduces pi-bonds; and there's P-2, which only partially reduces alkynes (stops at alkenes). It seems like Dr. Bergdahl only expects you to know about P-2, but ask just in case. P-2 nickel boride catalysts act in much the same way as Lindlar's catalyst, so you'll end up with a cis-alkene. Hope that helps!
