I don't understand the first 2 questions on this practice exam. How do I determine if something is more reactive? I can't decide whether or not resononce/activating/deactivating effects are most important in figuring out the fastest reaction or the most reactive species. the file attached has the questions.

Check your textbook. There is likely a section in the Diels-Alder reaction itself and if there is, there will be a portion about how electron withdrawing and donating groups effect the reactivity of the diene and dieneophile.

Although, if you know which - the diene or the dieneophile - is the nucleophile and electrophile you could work it out yourself.



For the second question, an Sn1 requires a carbocation intermediate. Which of those compounds could form the most stable intermediate?
