1.a
1.b
There are four isomers with the molecular formulaC4H9Cl. Only one of these isomers (compoundA) has a chiral center. When compound A is treated withsodium ethoxide, three products are formed: compounds B, C,and D. Compounds B and C arediastereomers, with compound B being the less stablediastereomer. Choose the correct structure for each compound(B,C,D).
1.c
Based on the above information fill the following blanks.
The structure contains a --------- (double bond, ring) due tothe IR having a signal that is ------ (<3000, >3000).
1H NMR signals fall between ------ (3.5-4, 5-6, 6.5-8).
13C signals fall between ------ range. (60-80 ppm, 110-140 ppm,150-200 ppm).
