Practical examples around us
| 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:
Ketones don't have that particular hydrogen atom, they are resistant to oxidation.
What you learn in Practice:
The presence of that hydrogen atom makes aldehydes very easy to oxidise.
