Organic Chemistry
1. Draw each one of the following molecules and label it as:
alkyl halide, allyl halide or vinyl halide
a) 2-chloro-3-ethylpentane
b) 6-ethyl-3-lodocyclohexene
2. Give all resonance structures of the allylic radical
intermediate that arise from reaction above. All allylic C-H on the
molecule are equivalent so only show the two resonance structures
arising from one C-H bond reacting.
3. Are the resonance structures above equivalent or
non-equivalent?
4. Give all the products expected from the reaction
above....

Học CH,Co? (5)-(1-bromopropyl)benzene (t)-1-phenylpropyl acetate The reaction of the chiral alkyl halide shown below with acetate gives a racemic mixture of acetate esters. A racemic product is formed in this reaction because O(S)-(1-bromopropylbenzene is a tertiary halide O(S)-(1-bromopropyl)benzene is a chiral molecule acetate is a weak nucleophile the reaction has occurred via a carbocation intermediate acetate is good nucleophile

Problem 10: Nucleophilic substitution is very prevalent in organic chemistry, in particular the SX2 reaction, in subsequent chapters of your textbook this reaction is prominently featured. In those instances the focus is on the nucleophile, rather than the alkyl halide, as we have been doing. By using different nucleophiles, nucleophilic substitution allows the synthesis of a wide variety of organic compounds with many different functional groups. With this in mind, draw the products of each two-step sequence. OH [1] NaH...
