Alkynes undergo many of the same reactions that alkenes do. What organic product(s) would you expect when the following compound is treated with 2 equiv Hz, Pd/C? CH3CH2CH2CH2CH2C=CCH3 • You do not have to consider stereochemistry • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right coner. • Separate multiple products using the - sign from the drop-down menu.
