show the mechanism of the following reaction step by step. Via Fischer esterification and transesterification.
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.

The following incomplete reaction sequences give a starting material and a product that can be prepared from it. Show the reagents taht would be necessary to carry out each transformation and any major products taht would be formed in the intermediate stages. There may be more than one correct way to complete a sequence. Thanks!
Would someone be able to draw the full mechanisms for these two reactions? Are these E1 or E2?
Propose a mechanism for the following transformation which occurs in this reaction? (provided in the image)
Rearrangements can occur during the dehydration of 1° alcohols even though no 1° carbocation is formed—that is, a 1,2-shift occurs as the C − OH2+ bond is broken, forming a more stable 2° or 3° carbocation, as shown. Using this information, draw a stepwise mechanism that shows how CH3CH2CH2CH2OH is dehydrated with H2SO4 to form a mixture of CH3CH2CH = CH2 and the cis and trans isomers of CH3CH = CHCH3. We will see another example of this type of rearrangement in Section 18.5C.
