Lesson: Types of Carbocations || Carboanion || Types of Carboanions ||  Attacking agents
About Lesson

Types of Carbocations :

Stability can be explained on the basis of +I effect –More the alkyl groups , more they release electrons and more the positive charge gets neutralized .Hence, more is the stability.

Organic Chemistry Class 11th Chapter 12 Notes and NCERT Solution.
Organic Chemistry

Carboanion

  1. They are Carbon with 8 e-.
  2. They are Electron rich.
  3. They act as Lewis base.
  4. They are Formed as a result of heterolytic fission.
  5.  

Types of Carboanions:

Organic Chemistry Class 11th Chapter 12 Notes and NCERT Solution.
  • More the alkyl group,more they release electrons and more intense the charge becomes.Hence, least will be the stability.

 Attacking agents

When the reaction occurs, attacking agent attacks and the product is formed.

 Type of attacking agents: They can be

  • Free radical : With unpaired electron
  • Nucleophile: With extra electrons. They also act as Lewis base and does Nucleus love. They are either:

Neutral with Lone pair: H2O , NH3 , NH2 , R – O – H , R – O – R

Negatively Charged: CN , X , OH

  • ElectrophileWith Positive charge has less electrons and act as Lewis acids. They are either :

Neutral: BF3 , BCl3 , AlCletc .

Positively charged: NH4, NO2+ , H3 Oetc .
