Which of the following is not true for carbanions?
Updated On: Apr 15, 2026
- The carbon carrying the charge has eight valence electrons
- They are formed by heterolytic fission
- They are paramagnetic
- The carbon carrying the charge is $sp^{3}$ hybridised
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Structure
Carbanions are negatively charged species where carbon has 8 valence electrons (6 from bonds + 2 in lone pair).
Step 2: Magnetic Property
Since all 8 electrons are paired (even number), carbanions are diamagnetic, not paramagnetic.
Step 3: Hybridization
The central carbon is typically $sp^{3}$ hybridised (pyramidal geometry).
Step 4: Formation
They are formed by the heterolytic cleavage of a covalent bond where carbon takes both electrons.
Final Answer: (C)
