A ketone is a functional group in organic chemistry with the formula R-C(=O)-R', where R and R' can be any number of carbon-containing substituents. A carbonyl group, or C(=O)-, or carbon-oxygen double bond, is present in ketones.
What is reagent?
Reagents are substances or mixtures that are added to a system in order to start a chemical reaction or determine whether one has already happened. A reagent can be used to test for the presence of a certain chemical by generating a reaction with it.
Reagents can be substances or combinations. Small inorganic or organic molecules make up the majority of compounds in organic chemistry. The Grignard reagent, the Tollens reagent, the Collins reagent, the Fehling reagent, and the Fenton reagent are examples of reagents. To be used as a reagent, a chemical does not necessarily need to contain the word "reagent" in its name.
