Study Notes
Classes of Organic Compounds
-
Alkane: Saturated hydrocarbons with the formula CnH2n+2, characterized by single bonds. Names end in -ane.
-
Alkene: Unsaturated hydrocarbons containing at least one carbon-carbon double bond, with the general formula CnH2n.
-
Alkyne: Compounds that feature carbon-carbon triple bonds. They are named by changing the suffix of the corresponding alkane from -ane to -yne. General formula is CnH2n-2.
-
Aromatic Compound: The simplest aromatic hydrocarbon is benzene, featuring a six-membered ring with alternating double bonds. When bonded to another group, it forms a phenyl group.
-
Alkyl Halide: Derived from alkanes where one hydrogen is replaced by a halogen (X= F, Cl, Br, I). Contains the functional group -X.
-
Alcohol: Contains a hydroxyl (-OH) group replacing a hydrogen atom. Classified as primary (1°), secondary (2°), or tertiary (3°) based on carbon atoms bonded to the carbon with the -OH group.
-
Ether: Compounds with an ether functional group represented as -OR, where R represents an alkyl group.
-
Amine: Contains an amino group (-NH₂). Classified as primary (1°), secondary (2°), or tertiary (3°) based on the number of carbon atoms attached to the nitrogen atom.
-
Thiol: Features a mercapto group (-SH), representing organic compounds with sulfur.
-
Sulfide: Contains an alkylthio group (-SR), indicating the presence of sulfur bonded to carbon.
-
Aldehyde: Characterized by the carbonyl functional group (C=O) located at the end of the carbon skeleton.
-
Ketone: A compound featuring a carbonyl group (R-CO-R), where there must be at least three carbon atoms present in the chain.
-
Carboxylic Acid: Defined by the carboxyl functional group (-COOH), marking it as an organic compound with distinguishing properties related to the -COOH group.
-
Ester: A derivative of carboxylic acids, typically formed from the reaction of an acid with an alcohol.
-
Amide: Compounds represented by the general formulas -CONH₂, -CONHR, or -CONR₂. They are derivatives of carboxylic acids where the -OH group is replaced by an amino group, with a planar structure and bond angles around 120°.
