Twin: The Aldehyde
Captions available
The idea
An aldehyde contains a carbonyl group, carbon double-bonded to oxygen, where the carbonyl carbon also bonds to at least one hydrogen, placing it at a chain's end.
In practice
Oxidizing 1-propanol's terminal –OH yields propanal, an aldehyde with its carbonyl at the chain's first carbon.
Where people slip
Confusing an aldehyde's end-of-chain carbonyl with its twin's mid-chain carbonyl is the exact error Chem 2466 exists to prevent.
