PUU DIAS formed as the leaving group is expelled from the a-carbon. This elimination follows Zaitsev's rule whereby the more substituted alkene is generally formed. In E2 elimination, both the B-hydrogen and the leaving group must be oriented anti to each other. The same reaction conditions apply for both Sy2 and E2, therefore these reactions often compete. Use of a strong, hindered base will tend to favor elimination, while use of a weak base/strong nucleophile will favor substitution. Draw curved...

Tulung ate n illud aludke place in a single step. In the Sn2 reaction, the nucleophile attacks the a-carbon from the backside and displaces the leaving group with an inversion of configuration occurring at the carbon. In the E2 elimination reaction, strong base removes an acidic hydrogen from the B-carbon and an alkene is formed as the leaving group is expelled from the a-carbon. This elimination follows Zaitsey's rule whereby the more substituted alkene is generally formed. In E2 elimination,...

Draw a reasonable, step by step arrow pushing mechanism for
the overall reaction. You may abbreviate non-involved parts of any
of the molecules with 'R' groups, and you can assume that water is
present in the reaction (to act as either an acid or a base).
