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 BH 3 . In this reaction, the multiple carbon–carbon bond has been replaced by the boron group and at last to OH group on addition of hydrogen peroxide.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 H 2 / Pt / pressure , or H 2 / Ni / 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 In this reaction, the multiple carbon–carbon bond has been replaced by a carbonyl group while azo compounds form nitrosamines.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 HgOAc . In this reaction, the multiple carbon–carbon bond has been replaced by the OH group. Alkenes or alkynes undergo halogenation reaction in the presence of halides like Br 2 and form substituted products.
