4. The choice of solvent for the reaction below can have a drastic effect on the rate. If we run one reaction in hexane and one reaction in THF, which one would you expect to go faster? Why? If you wanted the reaction to go even faster, what could you add to the reaction mixture? OLI LIHMDS pre HNOS er en Ph solvent Ph

Explain the effect of the solvent on the reaction kinetics with respect to an SN1 mechanism. How to explain 50%/50% acetone/water & 60%/40% acetone/water with reference to the above to the above (from results half life was way less in 50/50) According to the data chart, the Rate constant for the hydrolysis of tertbutylchloride in 50/50 acetone/water (volume) is: k=1.03E-2/min^1 The rate constant for the hydrolysis of tertbutylchloride in 60/40 acetone/water is: K=2.9E-3/min^-1

Reflux procedure and report 1) You start at the same time and in same devices reflux of 40 ml of hexane and in another one 40 ml of benzene. Which device will start reflux first? Explain 2) Why reflux is a referable method of running chemical reactions that require heating? Why not just heat your reaction content in the Erlenmeyer flask? 3) Why do we turn heat off first and water only after your device is at room temperature? 4)...

indicate which reaction will occur faster. explain
your reasoning. reaction of 1 chlorobutane with sodium iodide or
sodium p toluenesulfonate in aqueous ethanol.
Indicate which reaction will occur faster. Explain your reasoning. Select the single best answer Reaction of 1-chlorobutane with sodium iodide or sodium p-toluenesulfonate in aqueous ethanol Sodium iodide will react faster because the leaving group encounters less sterle hindrance. Sodium iodide will react faster because the intermediate is more stabilized in the solvent. Sodium p-toluenesulfonate will react...

(5 pts) Which of the following reactions is expected to produce 1-propanol (CH3CH2CH2OH) at the faster rate? Explain. NaOH, HEO CI- CI OH NaOH, acetone OH CI- (9pts) Consider the following substitution reaction. Br NaCN w DMSO Determine if the reaction is Sn1 or Sn2. Explain your choice. Write the rate equation for the reaction. Clearly include the structures of compounds in the formula. Would the process occur at a faster rate if the concentration of NaCN was doubled?
