Textbook Question
Chapter 9, Problem 9.41P
Elimination of HBr from 2-bromonorbornane gives only 2-norbornene and no 1-norbornene. How do you account for the regioselectivity of this dehydrohalogenation? In answering this question, you will find it helpful to look at molecular models of both 1-norbornene and 2-norbornene and analyze the strain in each.

1) Based on the Material Safety Data Sheets (MSDS) for the compounds, which of the compounds in this experiment is the most hazardous, and why (you have been given a representative aryl halide rather than all of the alkenes – as the products are all new, there’s not a simple answer to gauge their potential hazard)?
2,3-dihydrofuran,2-Mercaptobenzimidazole,Selectfluor, Dimethylformamide,dichloromethane-methylene chloride.
X
Upon ozonolysis, Compound X produces two compounds: Compound Y and
Compound Z. Compound Y can also be prepared from the following synthetic
route:
PCC

Compound Y
2.
CH₂Cl₂
2. NaOH, HO
CH₂Cl₂
3. H₂O*
From this information, draw the structures of Compounds X, Y, and Z. For
Compounds X and Z, different substituents are possible. For grading purposes,
just use hydrogens as the substituents.
