[2] Mechanism of Organic Reaction | Carbonation | Carbanion | Free Radical | Carbene | BSc 1st Year

For BSc 1st year students-
An organic reaction mechanism is a complete, step-by-step account of how a reaction of organic compounds takes place.
The description of an organic reaction mechanism typically includes designation of the overall reaction type (such as substitution, addition, elimination, oxidation, reduction, or rearrangement), the presence of any reactive intermediates, the nature of the reagent that initiates the reaction, the presence of any catalysis, and its stereochemistry.
A common method for showing the progress of a reaction is a potential energy diagram, which plots the free energy of the system as a function of the completion of the reaction. The highest point along the reaction pathway, called the transition state, indicates how easily the reaction can occur.
carbanion is an anion in which carbon is trivalent (forms three bonds) and bears a formal negative charge (in at least one significant resonance form).
Formally, a carbanion is the conjugate base of a carbon acid:
R3CH + :B− → R3C:− + HB
where B stands for the base. The carbanions formed from deprotonation of alkanes (at an sp3 carbon), alkenes (at an sp2 carbon), arenes (at an sp2 carbon), and alkynes (at an sp carbon) are known as alkyl, alkenyl (vinyl), aryl, and alkynyl (acetylide) anions, respectively.
In chemistry, a radical is an atom, molecule, or ion that has an unpaired valence electron. With some exceptions, these unpaired electrons make radicals highly chemically reactive. Many radicals spontaneously dimerize. Most organic radicals have short lifetimes.
In chemistry, a carbene is a molecule containing a neutral carbon atom with a valence of two and two unshared valence electrons. The general formula is R-(C:)-R' or R=C: where the R represent substituents or hydrogen atoms.
Methylene is the simplest carbene.
The term "carbene" may also refer to the specific compound H2C:, also called methylene, the parent hydride from which all other carbene compounds are formally derived.Carbenes are classified as either singlets or triplets, depending upon their electronic structure.

Mam 22:02 par :CH2 hoga na methylene instead of :CH3 ??

True, It's mistake . Aap sahi kr lena

Hello madam ye jo stability of carbanion me same process hi but yek me electron withdraw and second me electron release kyo ho raha? Please tell me..

Mam 17:18 par hybridisation sp3 hona chahiye na

Carbon radical is SP2 hybridizied with an unpaired single electron occupying an unhybridised p orbital.

Okay.. Dekho isme mene apko stability nikalni sikhai h carbanion ki. Agar 1 carbanion per hum ik grp asaa attach kree jo electron withdraw krega. Electron withdrawing grp Kya krega electron apni traff attract krega. Jisee carbanion per excess Jo charge h vo katam ho jayega or vo stable ho jayega... Second condition jab hum 1 carbanion per electron releasing grp laga de. Aab dekho carbanion per phle hi electron jyada hone ke Karan vo unstable h. Agar ik electron releasing attach krde usper to uski stability Kam ho jayegi.. Aage question Jo bhi krvaye h unko dekho apko samgh aa jayega. Thank you.
