chemistNATE・2 minutes read
Aldehydes and ketones have a double bonded oxygen, with aldehydes having it at the end of the carbon chain and ketones in the middle. Naming differences include aldehydes ending in "Al" and ketones in "ONE," with aldehydes taking precedence in naming over alcohols.
Insights
- Aldehydes and ketones differ in the position of the double-bonded oxygen: aldehydes have it at the end of the carbon chain, while ketones have it in the middle.
- Aldehydes are named with an "Al" suffix and take naming precedence over alcohols, while ketones use "ONE" and require a number to indicate the oxygen's position, showing their higher polarity compared to alcohols.
