Both aldehydes and ketone are planar to the neighborhoods of carbonyl (C=O) group. Which one of the following bonds is distorted towards the oxygen atoms?
Correct answer: A. π-bond of C and O
- A. π-bond of C and O
- B. Sigma bond of C and H
- C. Sigma bond of C and O
- D. sigma of C and C
Explanation
when we talk about the pi bond between the carbon (C) and oxygen (O) atoms in aldehydes and ketones, it's a bit "wonky" or distorted. This happens because oxygen is more electronegative than carbon, meaning it has a greater pull on the shared electrons in the bond. As a result, the electron density of the pi bond gets shifted or pulled more towards the oxygen atom. This creates a partial negative charge on oxygen and a partial positive charge on carbon. This distortion is what gives aldehydes and ketones their unique reactivity and properties.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
