We begin with the surmise that the nucleophilic substitution reactions can occur only by one of two mechanisms: Sn1 solvolysis: three-step mechanism R-X slow, R® + to R® + ROH fast , ROM R' H. R-O + R'OH fast , ROR' + R- SN2: one-step mechanism R-X + Nuc slow, Nuc-R + x Begin by answering the three questions below. If you don't understand what's up, please ask! 1. Write out the rate law for the above Sn1 reaction and...

2. (16 points) In each of the following pairs of reactions elimination competes with substitution. Write the starting material and all possible products of the reactions, don't write mechanistic part Write "elimination is favored" for reaction in which elimination products can be obtained in higher yield comparing to the yield of the elimination product/s in the second reaction. Provide the reason for such statement, reason is in reaction conditions. Supplementary session is on 10/31/19 between 5:30 PM an write an...
