Question

How to compare stability of carbanions ?

Explain please!!

Answer 1

the stability of carbanions also depends on d natue of hybridized orbitals used by d negatively charged carbon atoms.a more electronegative carbon atom accommodate a negative charge in a better ways and electronegativity of d c atom depends on d natue of hybridization its uses.

Answer 2

The stability and reactivity of a carbanion is determined by several factors. These include

1)The inductive effect. Electronegative atoms adjacent to the charge will stabilize the charge;

2)Hybridization of the charge-bearing atom. The greater the s-character of the charge-bearing atom, the more stable the anion;

3)The extent of conjugation of the anion. Resonance effects can stabilize the anion. This is especially true when the anion is stabilized as a result of aromaticity.

The stability of a carbanion also depends on the nature of hybridized orbitals used by the negatively charge carbon atom. A more electronegative carbon atom accomodates a negative charge in a betterways and electronegativity of the C atom depends on the nature of hybridization its uses. The primary carbanions more stable than secondary and tertiary carbanions.
