11.41 The aroma, taste, and general quality of wine are tied closely to the stage of development of the grapes from which it is made. In order to develop a molecular-level understanding of this phenomenon, the volatile components of cabernet sauvignon grapes were tested throughout their growth period. Among the many molecules detected, the concentration of (E)-2-hexenal was found to increase slowly for eight weeks from the flowering of the vine, then to spike for four weeks before decreasing again. Using the reaction described in Problem 11.34, propose a synthesis of (E)-2-hexenal starting from 1,1- dibromopentane. (E)-2-Hexenal

Can someone help with 11.41, please? 11.41 The aroma, taste, and general quality of wine are tied closely to the stage of development of the grapes from which it is made. In order to develop a molecular-level understanding of this phenomenon, the volatile components of cabernet sauvignon grapes were tested throughout their growth period. Among the many molecules detected, the concentration of (E)-2-hexenal was found to increase slowly for eight weeks from the flowering of the vine, then to spike for four weeks before decreasing again. Using the reaction described in Problem 11.34, propose a synthesis of (E)-2-hexenal starting from 1,1- dibromopentane. (E)-2-Hexenal please solve 11.41. reaction problem 11.34 is also listed as a reference 11.41 The aroma, taste, and general quality of wine are tied closely to the stage of development of the grapes from which it is made. In order to develop a molecular-level understanding of this phenomenon, the volatile components of cabernet sauvignon grapes were tested throughout their growth period. Among the many molecules detected, the concentration of (E)-2-hexenal was found to increase slowly for eight weeks from the flowering of the vine, then to spike for four weeks before decreasing again. Using the reaction described in Problem 11.34, propose a synthesis of (E)-2-hexenal starting from 1,1- dibromopentane. (E)-2-Hexenal 11.34 In the previous problem, we saw that an acetylide ion can attack a variety of electrophiles. In Chapter 19, we will see that a C-O bond can also function as an electrophile. Consider the following reaction between an acetylide ion (the nucleophile) and a ketone (the electrophile): R R 1) R R H-CEC 2) H,0 H. R R The acetylide ion attacks the ketone, generating an alkoxide ion. After the reaction is complete, a proton source is used to protonate the alkoxide ion. In a synthesis, these two steps must be shown separately, because the acetylide ion will not survive in the presence of H20. Using this information, propose a plausible synthesis for allyl alcohol (shown below), using acetylene as your only source of carbon atoms: HO,
