Methodologische Grundlagen der Biodiversit?te or sequence of bonding of the atoms in space are possible. Each individual molecular assembly is called an ., and the . of a compound is a particular combination of bonds and sequences of atoms of given molecular formula. For example, propanal, acetone, cyclopropanol, and 2-methyloxirane each corr

https://doi.org/10.1007/978-3-642-56739-1energetic consequences can be dissected and attributed to specific structural features. The features that are of greatest significance in organic chemistry are nonbonded interactions, both repulsive and attractive, and destabilization arising from distortion of bond lengths and angles from optimum v

Die Natur als Dienstleistungsbetriebolecules. Carbanions may vary widely in stability, depending on the ability of substituent groups to delocalize negative charge. In the absence of substituents that are effective in delocalizing the charge, proton abstraction from a C-H bond is very difficult.

Biodiversit?t gibt Sicherheit und Stabilit?tactions of the carbonyl group in organic synthesis. Most of the reactions of aldehydes, ketones, esters, amides, and other carboxylic acid derivatives are intimately associated with the carbonyl group. In Chapter 7, the role of the carbonyl group in stabilizing carbanion centers was discussed. The f
