Stability of Anions in GOC
How do you compare the stability of anions when the negative charge is present on different types of carbon atoms?
This JEE Main question from General Organic Chemistry asks students to examine three carbon anions and arrange them in the correct stability order. The key is to look closely at the carbon carrying the negative charge and understand how its hybridisation affects stability.
The Concept Behind the Question
Carbon atoms can have different hybridisations: sp³, sp² and sp. These differ in the amount of s-character in the orbital holding the lone pair.
When comparing the anions shown in the lesson, identify the negatively charged carbon in each structure first. Then examine its hybridisation before deciding the order. Reading the position of the charge correctly matters just as much as remembering the concept.
What You Will Learn
- How to identify the carbon bearing a negative charge
- How to determine sp³, sp² and sp hybridisation
- Why s-character matters in anion stability
- How to compare carbon anions systematically
- How to avoid common mistakes in JEE multiple-choice questions
