Reference: OCR
A curly arrow is drawn from the nucleophile's lone pair to the carbonyl carbon and a second arrow from the C=O π bond onto the oxygen, followed by protonation of the alkoxide.
The nucleophile adds to the carbonyl carbon and the π bond opens, giving a tetrahedral intermediate that picks up a proton.
