Stereochemistry and Isomerism

Stereochemistry deals with the three-dimensional structure and properties of molecules. It explains the arrangement of atoms and their manipulation within a molecule in a 3D structure. Stereochemistry can be dealt with all types of molecules. Based on the stereochemistry of a molecule, the physical and chemical properties of the molecules vary.

SN1 reactions are better performed in protic solvents. Explain why the researchers could not perform the reaction using 100% water as solvent instead of 50% aqueous acetone.
Alcohols react with sulfonyl chlorides to form sulfonate esters. Only the O-H bond of the alcohol is broken in the reaction, and so no inversion of configuration occurs. The resulting sulfonate esters are reactive in SN1 and SN2 reactions since the sulfonate group is a very weak base and is therefore a good leaving group.Draw curved arrows to show the movement of electrons in this step of the mechanism.
Which is the better retrosynthesis for the given target molecule? Explain, and provide a one-step synthesis of the target molecule. A A is the better starting material because B can form both E and Z alkenes. B A is the better starting material because it will produce only the desired target molecule. C B is the better starting material because only B has β protons in the trans position. D B is the better starting material because A can form both E and Z alkenes. E B is the better starting material because it will produce only the desired target molecule. F A is the better starting material because only A has β protons in the trans position.
True or false 1.Hydroxide is the good leaving group for SN2 reaction. 2.Iodide ion is the better leaving group than the bromide ion. 3.Ethyl bromide is the better substrate than t-butyl bromide for SN2 reactions. 4.water is the protic solvent. 5.Sn1 reactions take place in one single step.

The use of curved arrows is a powerful tool that illustrates even complex reactions. a.Add curved arrows to show how carbocation A is converted to carbocation B. Label each new σ bond formed. Similar reactions have been used in elegant syntheses of steroids. b.Draw the product by following the curved arrows. This reaction is an example of a [3,3] sigmatropic rearrangement, as we will learn in Chapter 25.
