Nucleophilic addition to the carbonyl

The C=O bond is polarized: oxygen pulls density, so the carbon carries a partial positive charge and welcomes nucleophiles.

Nu− + R2C=O → R2C(O−)Nu → R2C(OH)Nu

Aldehydes react faster than ketones. Less steric bulk at the carbon, and only one alkyl group pushing electrons in.

Recall Why does hydration favour formaldehyde over acetone?

Why are aldehydes more electrophilic than ketones?tap to flip
One alkyl group instead of two: less electron donation into the carbonyl and less steric crowding at the carbon.

Slide 9 of 14 Hemiacetal formation
  • Alcohol attacks the carbonyl carbon
  • Proton transfer gives the hemiacetal
  • Acid catalysis speeds the second addition

Theo: So the alcohol is the nucleophile this time, and the carbonyl carbon is still the one taking the hit.

Ask Sendyknows all 3 classes
Which units in Orgo and Biochem both cover enzyme catalysis? I have both exams next week.
Two overlaps. Orgo Unit 4 covers acid-catalysed carbonyl addition, and Biochem Unit 3 reuses the same mechanism for serine proteases. Study them together: the tetrahedral intermediate shows up in both. Open Orgo Unit 4 notesPractice test, both units
