Here's why:
* Hydrocarbon: A molecule composed primarily of hydrogen and carbon atoms.
* Carbonyl group: A functional group consisting of a carbon atom double-bonded to an oxygen atom (C=O).
* Aldehyde: A molecule containing a carbonyl group at the end of a carbon chain.
Key features of aldehydes:
* The carbonyl group is always at the end of the carbon chain.
* The carbon atom of the carbonyl group is bonded to one hydrogen atom.
* The general formula for an aldehyde is R-CHO, where R is a hydrocarbon group.
Examples of aldehydes:
* Formaldehyde (HCHO): The simplest aldehyde, used in preservatives and disinfectants.
* Acetaldehyde (CH3CHO): A volatile liquid found in some fruits and used in the production of acetic acid.
* Benzaldehyde (C6H5CHO): Found in almonds and used in perfumes and flavorings.
