What is organic chemistry?
- To the organic chemist this is a meaningless distinction. There are toxic compounds and nutritious ones, stable compounds and reactive ones—but there is only one type of chemistry: it goes on both inside our brains and bodies and also in our flasks and reactors, born from the ideas in our minds and the skill in our hands.

26) This mechanism is best approached by working backwards. The product shown is an ether-bromide,
with the oxygen and the bromine atoms on adjacent carbons. Every time two functional groups are onadjacent carbons it suggests the possibility that they might be formed by an addition to the C=C double
bond. This can be represented generically thus: AB AB An addition of bromine in the presence of water produces such result, adding Br to one carbon andOH to the other (section 8-11 in the textbook).
OHBr Br 2 H 2 O This suggests the possibility that an alcohol could be used instead of water, with similar results, except that this would add Br to one carbon and RO to the other one. ORBr Br 2 ROH The mechanism of this reaction would be similar to that with water. Bromine adds first to form a three memebered ring intermediate, followed by nucleophilic attack by the alcohol from the back.Let's use an unsymmetrical alkene to illustrate the point that the most highly substituted carbon gets
the RO group preferentially. BrBr Br HOR O HR Br Br RO Br HBr The molecule in question has an oxygen (ether group) and a bromine on adjacent carbons. We can make a similar reasoning as above that such arrangement forms from the reaction between a C=C bond and Br 2 in the presence of an alcohol, a group that also happens to be present in the starting material. HO O BrThe ether and bromine groups are on adjacent
carbons, suggesting that the original double bond was between C 1 and C 2.Notice the oxygen on C
5 1 2 3 4 5 1 2 3 4 5The starting material also happens to have
5 carbons, with the double bond on C
1 and C 2 and the oxygen on C 5. With this scenario in place, we can now start the mechanism from the first step, which would be the attack of the pi-bond on bromine to form a three membered ring intermediate. HO 1 2 3 4 5 BrBr HO 1 2 3 4 5 Br Br The alcohol group is now poised to attack the three membered ring at the most highly substituted carbon. The carbon chain is long enough to allow for flexibility of movement without introducing strain. O 1 2 3 4 5 Br Br O Hquotesdbs_dbs9.pdfusesText_15[PDF] organic nomenclature packet chemistry answers
