4. For each reaction, look at all the reagents and conditions, and determine if the reaction will proceed via an SN1 or SN2 reaction. a) b) Br c) CI H₂O Fo 0=8=0 CH3 DMSO CH3OH

How do you solve this mechanism?

For each of the following processes predict the sign of AS for the reaction. In other words, will AS sys be positive (an increase in entropy) or negative (a decrease in entropy)? AS sys is expected to be positive (an increase in entropy) because one molecule is converted into two molecules. AS sys is expected to be negative (a decrease in entropy) because a cyclic compound is converted into acyclic compounds. O AS sys is expected to be positive (an increase in entropy) because an acyclic compound is converted into cyclic compounds. O AS sys is expected to be negative (a decrease in entropy) because two molecules are converted into one molecule.

step(s). The SN2 reaction of chloroethane with NaC=CH has 1
