Retrosynthesis: When No2 bond breaks, which one would be the next better leaving group, SO3H or cyclopentane?    Why is SO3H a better leaving group than cyclopentane?   Why NO2 is the first one that leave in Retrosynthesis, what make NO2 a better leaving group over SO3H or cyclopentane?

Associate the reaction mechanism with the indicated characteristics of the base or nucleophile. Assume that the electrophile bears a good enough leaving group. E2 1. Species is a strong nucleophile but a weak base Could be SN1 or E1, depending on the electrophile's structure 2. Species is a weak nucleophile but a strong base 3. Species is a strong nucleophile and a strong base SN2 Could be SN2 or E2, 4. Species is a weak nucleophile and a depending on the electrophile's structure weak base >

This is a stereochemistry consideration –how the atoms add with regard to space (R/Sand E/Z).
