An introduction to carbonyl compounds Flashcards
1
Q
What is the carbonyl functional group? What types of organic compounds contain it?
A
- A carbonyl functional group has a C=O bond. - Aldehydes and ketones have this functional group.
2
Q
What does a C=O ( carbonyl bond ) consist of? (pie/sigma stuff)
A
- Contains a sigma bond and a pie bond. - The sigma bond is formed by the overlap of orbitals between the C and O atoms. The pie bond is formed by the overlap of the p-orbitals on the carbon and oxygen atoms in the carbonyl bond.
3
Q
Why does a carbonyl bond not react in the same way as the double bond in an alkene?
A
The oxygen atom is more electronegative than the carbon atom. This creates a dipole in the C=O bond because the bonded electrons are attracted towards the oxygen.
4
Q
Define the term “stem”.
A
The stem is longest carbon chain present in an organic molecule.
5
Q
What are aromatic aldehydes and ketones?
A
Aromatic aldehydes and ketones are compounds containing both a benzene ring and a carbonyl group.
6
Q
Draw the simplest aromatic aldehyde.
A
- benzaldhyde
7
Q
Draw and name the simplest aromatic ketone.
A
- phenylethanone
