2. Carbanion - Wikipedia

   en.wikipedia.org/wiki/Carbanion

   Formally, a carbanion is the conjugate base of a carbon acid: R 3 CH + B − → R 3 C − + HB. where B stands for the base. The carbanions formed from deprotonation of alkanes (at an sp 3 carbon), alkenes (at an sp 2 carbon), arenes (at an sp 2 carbon), and alkynes (at an sp carbon) are known as alkyl, alkenyl , aryl, and alkynyl anions ...

3. Carbon–carbon bond - Wikipedia

   en.wikipedia.org/wiki/Carbon–carbon_bond

   Carbon is one of the few elements that can form long chains of its own atoms, a property called catenation.This coupled with the strength of the carbon–carbon bond gives rise to an enormous number of molecular forms, many of which are important structural elements of life, so carbon compounds have their own field of study: organic chemistry.

4. Carbon compounds - Wikipedia

   en.wikipedia.org/wiki/Carbon_compounds

   In general bonds of carbon with other elements are covalent bonds. Carbon is tetravalent but carbon free radicals and carbenes occur as short-lived intermediates. Ions of carbon are carbocations and carbanions are also short-lived. An important carbon property is catenation as the ability to form long carbon chains and rings. [3]

5. Reaction intermediate - Wikipedia

   en.wikipedia.org/wiki/Reaction_intermediate

   A carbanion is an organic molecule where a carbon atom is not electron deficient but contain an overall negative charge. Carbanions are strong nucleophiles, which can be used to extend an alkene's carbon backbone in the synthesis reaction shown below. [5] C 2 H 2 with NaNH 2 in NH 3 (l) → CHC − CHC − + BrCH 2 CH 3 → CHC−CH 2 CH 3

6. List of straight-chain alkanes - Wikipedia

   en.wikipedia.org/wiki/List_of_straight-chain_alkanes

   The following is a list of straight-chain alkanes, the total number of isomers of each (including branched chains), and their common names, sorted by number of carbon atoms. [ 1 ] [ 2 ] Number of C atoms

7. E1cB-elimination reaction - Wikipedia

   en.wikipedia.org/wiki/E1cB-elimination_reaction

   The compound must have an acidic hydrogen on its β-carbon and a relatively poor leaving group on the α- carbon. The first step of an E1cB mechanism is the deprotonation of the β-carbon, resulting in the formation of an anionic transition state, such as a carbanion. The greater the stability of this transition state, the more the mechanism ...
