Best ResponseYou've already chosen the best response.0@Cuanchi seeing these reactions by themselves isn't as hard but when asked to identify whether E1/E2 SN1/SN2 it's not quite straightforward.

Best ResponseYou've already chosen the best response.0@Photon336 I never understood the E1/E2 SN1/SN2 I should read again organic substitutions and RMN, IR spectroscopy

Best ResponseYou've already chosen the best response.0@cuanchi i feel there's a fine line between a base and nucleophile, that's one thing i have problems with especially in these types of questions. also some of the rules for SN2 as well become fuzzy when we deal with like secondary substrates.

Best ResponseYou've already chosen the best response.0I never said that substitution reaction wouldn't occur. As you slowly increase temperature though, elimnation reaction wins over substitution. this doesn't mean that its going to be 100% substitution or 100% elimination. as you increase temp, more energy is available. thus, the starting material can jump the activation barier better to result in elimination reaction thermodynamically favoirable. the full reaction, elimination begins with one, and results in 3 products (generally). whereas substitution = 2 products gibbs equation tells us there's increase in entropy as a result. the change in gibbs will evntually rule out making elimination more favorable.
