The United States National Chemistry Olympiad (or USNCO) is a contest held by the American Chemical Society (ACS) used to select the four-student team that represents the United States at the International Chemistry Olympiad (IChO). Each local ACS section selects 10 students (or more for larger ACS sections) to take the USNCO National Exam. To ...
In 1874, a group of American chemists gathered at the Joseph Priestley House to mark the 100th anniversary of Priestley's discovery of oxygen.Although there was an American scientific society at that time (the American Association for the Advancement of Science, founded in 1848), the growth of chemistry in the U.S. prompted those assembled to consider founding a new society that would focus ...
The Journal of Organic Chemistry, colloquially known as JOC, is a peer-reviewed [1] scientific journal for original contributions of fundamental research in all branches of theory and practice [2] in organic and bioorganic chemistry. It is published by the publishing arm of the American Chemical Society, with 24 issues per year.
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [1]
Organic Letters is a biweekly peer-reviewed scientific journal covering research in organic chemistry. It was established in 1999 and is published by the American Chemical Society. In 2014, the journal moved to a hybrid open access publishing model. The founding editor-in-chief was Amos Smith. The current editor-in-chief is Marisa C. Kozlowski. [1]
The aldol reaction (aldol addition) is a reaction in organic chemistry that combines two carbonyl compounds (e.g. aldehydes or ketones) to form a new β-hydroxy carbonyl compound. Its simplest form might involve the nucleophilic addition of an enolized ketone to another: Prototype aldol reaction
The last image we have of Patrick Cagey is of his first moments as a free man. He has just walked out of a 30-day drug treatment center in Georgetown, Kentucky, dressed in gym clothes and carrying a Nike duffel bag. The moment reminds his father of Patrick’s graduation from college, and he takes a picture of his son with his cell phone.
