A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
In chemistry, a reactivity series (or reactivity series of elements) is an empirical, calculated, and structurally analytical progression [1] of a series of metals, arranged by their "reactivity" from highest to lowest.
In one study [2] the reactivity of two different free radical species (A, sulfur, B carbon) towards addition to simple alkenes such as acrylonitrile, vinyl acetate and acrylamide was examined. The sulfur radical was found to be more reactive (6*10 8 vs. 1*10 7 M −1 .s −1 ) and less selective (selectivity ratio 76 vs 1200) than the carbon ...
This series, and perhaps your confusion relating to the UK-US difference, is a RE-activity series, where most likely an American text book will show you an Activity series. If sodium is to be placed above potassium then what about ceasium and francium? 182.55.242.11 ( talk ) 14:17, 9 July 2011 (UTC) K is indeed more reactive than Na, which is ...
The reactivity of a functional group can be modified by other functional groups nearby. Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis . A functional group is a group of atoms in a molecule with distinctive chemical properties , regardless of the other atoms in the molecule.
Like the book, the series tells the story of Elizabeth Zott (Brie Larson), a young woman who’s dead-set on working as a chemist despite the odds stacked against her in 1950s America.
The Oxford Chemistry Primers are a series of short texts providing accounts of a range of essential topics in chemistry and chemical engineering written for undergraduate study. The first primer Organic Synthesis: The Roles of Boron and Silicon was published by Oxford University Press in 1991. [ 1 ]
The condensed Fukui function or condensed reactivity indicator is the same idea, but applied to an atom within a molecule, rather than a point in three-dimensional space. The Fukui function allows one to predict, using density functional theory , where the most electrophilic and nucleophilic sites of a molecule are.
