Chapter 8, Problem 27P

Interpretation Introduction

Interpretation:

The structures of the products formed when 1-methylcyclopentene reacts with the given reagents are to be written.

Concept Introduction:

Hydroboration-oxidation: An organic reaction in which the double bonds of alkenes or alkynes are broken by ${\text{BH}}_3$. In this reaction, the multiple carbon–carbon bond has been replaced by the boron group and at last to $\text{OH}$ group on addition of hydrogen peroxide.

Reduction is a process in which hydrogen atoms are added to a compound.

Usual reagents used in the reduction process are ${\text{H}}_2/\text{Pt}/\text{pressure}$, or ${\text{H}}_2/\text{Ni}/\text{pressure}$.

Ozonolysis: An organic reaction in which the double bonds of alkenes, alkynes, or azo compounds are broken by ozone. In this reaction, the multiple carbon–carbon bond has been replaced by a carbonyl group while azo compounds form nitrosamines.

Oxymercuration-demercuration: An organic reaction in which the double bonds of alkenes or alkynes are broken by $\text{HgOAc}$. In this reaction, the multiple carbon–carbon bond has been replaced by the $\text{OH}$ group.

Alkenes or alkynes undergo halogenation reaction in the presence of halides like ${\text{Br}}_2$ and form substituted products.
