How to pronounce“carbanion”in English

The carbanion in the organometallic compound attacks the carbonyl carbon, pushing electrons up to that electronegative oxygen so it has three lone pairs and a negative charge.

And protonating this carbanion gives us the alkylbenzene product we’re looking for.

specifically a negatively charged carbanion attached to an atom with a positive charge.

We use the carbanion resonance form, attack the proton on a water molecule, and reform the base to make our keto form.

Now we have a resonance-stabilized carbanion that gets protonated to form the neutral enol product, when some acid is added.

so the reactivity of these carbanions can help.

But the other part of the hybrid is an alpha-keto carbanion – that is, a carbonyl group bonded to a negatively charged carbon.
