McMurry's most popular textbook Organic Chemistry was first printed in 1984. In 2022, he sold the rights for the book to OpenStax making it free for the user. [3] [4] Among his other texts are: Organic Chemistry with Biological Applications (3rd edition) [5] Chemistry (8th edition) [6] General Chemistry, Atoms First (2nd edition) [7]
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Jimmy Wales has described Wikipedia as "an effort to create and distribute a free encyclopedia of the highest possible quality to every single person on the planet in their own language". [W 49] Though each language edition functions more or less independently, some efforts are made to supervise them all. They are coordinated in part by Meta ...
Inorganic compounds exhibit a range of bonding properties. Some are ionic compounds, consisting of very simple cations and anions joined by ionic bonding.Examples of salts (which are ionic compounds) are magnesium chloride MgCl 2, which consists of magnesium cations Mg 2+ and chloride anions Cl −; or sodium hydroxide NaOH, which consists of sodium cations Na + and hydroxide anions OH −.
Chemical Society Reviews publishes "Tutorial reviews" and "Critical reviews". The former are written to be of relevance both to the general research chemist who is new to the field, as well as the expert, whereas the latter aim to provide a deeper understanding of the topic in hand, but retain their accessibility through an introduction written for the general reader.
Analytical chemistry has been important since the early days of chemistry, providing methods for determining which elements and chemicals are present in the object in question. During this period, significant contributions to analytical chemistry included the development of systematic elemental analysis by Justus von Liebig and systematized ...
