Q4a - The reaction of butan-2-ol with concentrated aqueous HBr goes with partial racemization, giving more inversion than retention of configuration. Propose a mechanism that accounts for partial inversion. Draw all the arrows to indicate movement of electrons, write all lone pairs involved into electron transfer, all formal charges, and all the products for each step. If a racemic mixture is formed, you may indicate this using a wavy line www or mark the chiral center with an asterisk (*),...

Consider the two reactions below for the optically active alkyl halide, (R)-2-chloropentane. The first reaction occurs rapidly at room temperature and gives an optically active product. The second reaction, starting with the same alkyl halide, occurs slowly at room temperature and gives a non-optically active product (racemic mixture). Draw a mechanism (include all H's and lone pairs) for cach reaction and explain how the mechanism leads to the observed results. Hics CHES- CH.OH CH,OH
