LibreTexts (formerly called STEMHyperlibrary[1] and ChemWiki[2]) is a 501 (c) (3) nonprofit [3] online educational resource project. The project provides open access to its content on its website, and the site is built on the Mindtouch platform. [4] LibreTexts was started in 2008 by Professor Delmar Larsen at the University of California Davis ...
Syn and anti addition. In organic chemistry, syn- and anti-addition are different ways in which substituent molecules can be added to an alkene (R2C=CR2) or alkyne (RC≡CR). The concepts of syn and anti addition are used to characterize the different reactions of organic chemistry by reflecting the stereochemistry of the products in a reaction.
The CNX platform was retired [40] in 2020, when OpenStax transitioned to the use of Google Docs instead. LibreTexts is a nonprofit OER (online educational resource) project. Content from LibreTexts is made available under the CK-12 Foundation Curriculum Materials License. [41]
Organic synthesis is a branch of chemical synthesis concerned with the construction of organic compounds. Organic compounds are molecules consisting of combinations of covalently-linked hydrogen, carbon, oxygen, and nitrogen atoms. Within the general subject of organic synthesis, there are many different types of synthetic routes that can be ...
In regression analysis, logistic regression[1] (or logit regression) estimates the parameters of a logistic model (the coefficients in the linear or non linear combinations). In binary logistic regression there is a single binary dependent variable, coded by an indicator variable, where the two values are labeled "0" and "1", while the ...
Oscillation. Repetitive variation of some measure about a central value. An undamped spring–mass system is an oscillatory system. Oscillation is the repetitive or periodic variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states.
Increasingly, LibreTexts topics are being cited in articles, at least in the chemistry project. It is a favorite for students doing homework. The articles in LibreTexts lack references, as far as I can see. I doubt that these references are reliable.
In chemistry, a molecular orbital (/ ɒrbədl /) is a mathematical function describing the location and wave-like behavior of an electron in a molecule. This function can be used to calculate chemical and physical properties such as the probability of finding an electron in any specific region.
