The document explains how to determine the reaction mechanism and major product of a reaction. It involves a tertiary alkyl halide in an aprotic solvent. This indicates the reaction will proceed by an E1 mechanism, not Sn2, forming a carbocation intermediate. The most stable carbocation and most favored major product will be the secondary carbocation according to Zaitsev's rule.

1. Hey I couldn't click on it so I will explain it to you. The first thing you do is look
at what they give you a) A tertiary alkyl halide, This means there is no chance that this can go
sn2. very likely to go E2, So most probably Sn1/E1. b) The solvent is aprotic because it has a
Hydrogen that will easily leave, mostly seen in water, alcohols, acids etc. So no we are sure that
it is Sn1/E1 c) look at your answers do you see any substitutions? NO..so this is an E1
mechanism. d) the first products that pops to your head are the second and fourth (answer for
part A) e) Now we know that E1 mechanisms go through carbocation intermediates, and we
know that carbocations according to Zaistev's Rule is Tertiary>Secondary>Primary..So naturally
your major product is the more stable one, which is the second one (answer to part b) Good luck
