Aldehydes and Ketines : Nucleophilic Addition Reactions
Aldehydes and ketones are among the most widely occurring of all compounds, both in nature and in the chemical industry. In anture, many substances required by liveing oranisms are aldehydesor ketones. In the chemical industry, simple aldehydes and ketones are produced in large quantities for use as solvents and as starting materials to prepare a host of other compounds.
