Real Life Question:

What are Aldehydes?

Key Words / FlashCards
Key Words Definitions (pref. in our own words)
Aldehydes An organic compound containing a formyl group. This functional group, with the structure R-CHO, consists of a carbonyl center (a carbon double bonded to oxygen) bonded to hydrogen and an R group, which is any generic alkyl or side chain.

Examples Explainations
ketones In general ketones (R-CO-R) take the suffix "-one" (pronounced own, not won) with an infix position number: CH3CH2CH2COCH3 is pentan-2-one. If a higher precedence suffix is in use, the prefix "oxo-" is used: CH3CH2CH2COCH2CHO is 3-oxohexanal.
What you learn in Theory:

In this generalized reaction the a-carbon of one aldehyde forms a bond with the carbonyl carbon of the other aldehyde. 2 Acetaldehyde + Sodium ethoxide ---> Aldol (a b-hydroxy aldehyde)

What you learn in Practice:

The aldol condensation is a reaction in which aldehydes and ketones react to form larger molecules. A new carbon-carbon bond is formed.
