What is the order of primary, secondary and tertiary anions? I know that an acetylide anion is more stable than a vinylic anion, which is more stable than an alkyl anion. From that I'd guess that a less substituted carboanion would be more stable than a higher substituted one. Is this right?
I think a tert-butyl carbanion would not be stable since the 3 methyl group would donate electron density towards the anion (less stable). And in primary carbanion (grignards) are stable due to less of this donation of electron density
