Can someone help me with this please?
What is the major reason for the 1-butanol starting material having a higher boiling point than the isolated 1-bromobutane product even though the molar mass of 1-butanol is only about half that of the 1-bromobutane? Explain, with reference to the relevant intermolecular forces for each of the samples. Your explanation should include a diagram to illustrate the most important intermolecular force for each liquid. B.P. Molar mass 1-butanol 118 degree C 74.12 g 1-bromobutane 102 degree C 137.03 g In addition to the major product (1-bromobutane) there are a number of side products which can be formed in this reaction. Assuming that the substitution reaction (S_N2) is in competition with elimination (via the E2 mechanism), deduce the structure of the resulting alkene. The alkene formed in part a) can be protonated resulting in the formation of a carbocation. Draw the carbocation. The carbocation in part b) can then react via S_N1 or E1 to yield a number of substitution and elimination products. Deduce the products formed under the following conditions. Some of the reactions may produce stereoisomers. The reaction of the carbocation with bromide ion (SN1 conditions). Include stereoisomers and name them using the R/S system. The reaction of the carbocation with water (SN1 conditions). Include stereoisomers and name them using the R/S system. - draw only the final structures produced after deprotonation of the reaction intermediate. The reaction of the carbocation with any weak base to yield an alkene (via E1 mechanism). There are three potential alkenes formed, if we consider structural isomers and geometric isomers (cis-trans). Deduce the structures of all three alkenes and name them. If we assume that the most important side reaction is the elimination reaction shown in part e), what is the major side product for this reaction? (i.e. Which of the alkenes is the major side product?)
