ExplainAdol Condensation Lab, Organic Chemistry 2: The same physical property that helps drive the reaction to completion can also stall out the reaction before it starts. What do we do in the procedure that helps minimize this concern? (initially I said that the driving force is 1) reactivity of carbonyl compounds 2) stability of the product please be as detailed as possible, will mark as helpfulI need help with drawing the major product(s) of hexane, iodine and light please
- 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 in Equation [1]. Using this information, draw a stepwise mechanism for the reaction shown in Equation [2]. We will see another example of this type of rearrangement in Section 16.5C.Please help with the mechannismFill in the fields (reagent or products) left blank in the reaction below.
