Frequently Asked Questions
What are organic compounds?
Organic compounds are chemical compounds containing carbon atoms, typically bonded to hydrogen, oxygen, nitrogen, or other elements. They form the basis of all living matter and are central to chemistry, biology, and industry.
What is a functional group?
A functional group is a specific arrangement of atoms within a molecule that determines its chemical properties and reactivity. Each class of organic compound is defined by its characteristic functional group.
How are organic compounds named?
Organic compounds are named following the IUPAC (International Union of Pure and Applied Chemistry) system. Names are based on the parent carbon chain length, the type of functional group, and the position of substituents.
What is the difference between aldehydes and ketones?
Both contain a carbonyl group (C=O), but in aldehydes it is at the end of the carbon chain (terminal), while in ketones it sits between two carbon atoms (internal). This difference makes aldehydes more reactive toward oxidation than ketones.
What is the difference between carboxylic acids and esters?
Carboxylic acids contain a free -COOH group and are acidic. Esters are formed when the hydrogen of the -OH in a carboxylic acid is replaced by a carbon group from an alcohol, giving the characteristic -COO- linkage.
