Show how you would accomplish the following synthetic conversions.
(a)1-iodo-2-methylcyclopentaneS1-methylcyclopentanol
(b)3-methylpent-1-eneS3-methylpentan-2-ol
Predict the major products of the following reactions, and propose mechanisms to sup-port your predictions.
1-phenylpropene + HBr + di-tert-butyl peroxide
When 1 mole of buta-1,3-diene reacts with 1 mole of HBr, both 3-bromobut-1-ene and 1-bromobut-2-ene are formed. Propose a mechanism to account for this mixture of products.
Explain why the + charge of the carbocation always appears at the carbon of the (former) double bond that has NOT bonded to the electrophile.
What are racemic mixtures? Discuss their resolution involving the formation of diastereomers.

(2) Outline the mechanism of the reaction when the alkyl halide reacts with sodium ethoxide.Name the product according to the IUPAC rules.


(3) Draw the structure of 2,2-dichloroethanoic acid.Is 2,2-dichloroethanoic acid a stronger or weaker acid than ethanoic acid?Motivate your answer


Predict the major products of the following reaction. Include stereochemistry where applicable.
trans@4,4@dimethylpent@2@ene + BH3 # THF, then O2, OHH2 (c) H O2, OH

In the hydroboration of 1-methylcyclopentene shown in Solved Problem 8-3, the reagents are achiral, and the products are chiral. The product is a racemic mixture of trans-2- methylcyclopentanol, but only one enantiomer is shown. Show how the other enantiomer is formed.
