3. Beginning with an alcohol and an alkyl halide, draw two different routes to each of the following ethers using a Williamson ether synthesis (Smith 9.6). Indicate the preferred route (if there is one). Predict the products of dehydration (elimination) of the following alcohol. Read Smith 9.8A. Predict which product will be the major product. H.SO 2-pentanol Write a mechanism for the dehydration reaction (steps showing the flow of electrons with curved arrows). Read Smith 9.8B & 9.9. 2-methylcyclopentanol

Based on the Wittig Reaction exp. below, please answer a) and
b). In b) you can disregard the part about the IR, just please
interpret and assign protons, shift values, which protons are for
which groups, etc on the HNMR. The % yield was 34%, and MP was
lower than expected (to assist with answering part a). This should
be all the information you need to answer the question.

1.)
2.)
A person can take either of two routes to work, through Matteson or Richton Park. Both take on average 35 minutes, and travel times are Normally distributed. But are the variances of the travel times different? A random sample with n = 8 using the Matteson route, and another random sample with n = 6 using the Richton Park route, showed a variance of 40 (units: square minutes) and 30 respectively. To test whether the variances are different,...

Two
different and independent bus routes come to the same stop then
both continue to the train station. From route X there are
typically 2.5 buses arriving every 10 minutes. While buses from
route Y will arrive at the stop with uniform randomness anywhere
from between 0 and 9 minutes since the last bus from route Y.

Southway Shuttle provides a shuttle service from Lincoln Heights to the airport. There are two routes that the shuttle can take: Highway 40 and Tall Pine Road, Southway is looking to determine if either route tends to be faster and of time of day--morning or evening--makes a difference. For each route, Southway chose an equal number of moming trips and evening trips and recorded their durations (the time it took for the trip, in minutes). Then the company computed the...

Part A The rate of the reaction in terms of the "disappearance of reactant" includes the change in the concentration of the reactant, the time interval, and the coefficient of the reactant Consider the following reaction: 2A + 3B 3C + 2D The concentrations of reactant A at three different time intervals are given. Use the following data to determine the average rate of reaction in terms of the disappearance of reactant A between time=0s and time = 20 S....
