Study Notes
Functional Groups in Organic Chemistry
-
Alcohol: Organic compounds characterized by the presence of a hydroxyl (-OH) group.
-
Aldehyde: Contains a carbonyl group (C=O) with a hydrogen atom attached, typically at the end of a carbon chain.
-
Ketone: Features a carbonyl group (C=O) bonded to two carbon atoms, typically found within a carbon chain.
-
Carboxylic Acid: Contains a carboxyl group (-COOH), exhibiting acidic properties due to the presence of the hydroxyl and carbonyl groups.
-
Ester: Formed from a reaction between a carboxylic acid and an alcohol, characterized by the -COO- group.
-
Amide: Derived from carboxylic acids where the -OH group is replaced by an amine or ammonia, featuring the -CONH2 group.
-
Anhydride: Formed by the dehydration of two carboxylic acids, contains two acyl groups bound to the same oxygen atom.
Priority of Functional Groups
- Functional groups ranked in decreasing order of priority for naming:
- Carboxylic acid
- Anhydride
- Ester
- Amide
- Aldehyde
- Ketone
- Alcohol
- Alkene
- Alkyne
- Alkane
Common Alkyl and Acyclic Groups
-
Methyl: A one-carbon (CH3) substituent derived from methane.
-
Ethyl: A two-carbon (C2H5) substituent derived from ethane.
-
Phenyl: A cyclic group derived from benzene, represented as C6H5; often reacts as an aromatic substituent.
-
Acetyl: An important functional group derived from acetic acid, characterized by the -COCH3 structure.
Additional Functional Groups
-
Enol: Contains a carbon-carbon double bond adjacent to a hydroxyl group; less stable than its keto form.
-
Ether: Comprised of two alkyl or aryl groups connected through an oxygen atom (-R-O-R').
-
Amino: Contains an amine group (-NH2), often a basic part of amino acids.
-
Amido: Related to amides, where the functional group also includes an amine.
-
Imine: Features a carbon-nitrogen double bond (C=N), formed by the condensation of an amine and a carbonyl compound.
-
Schiff Base: A specific type of imine formed from the reaction of an amine and a carbonyl compound.
-
Sulfhydryl: Contains a thiol group (-SH), important in the structure of some proteins and enzymes.
-
Disulfide: Comprising two sulfhydryl groups that form a -S-S- bond, often found in protein structures.
-
Thioester: Similar to esters, but with a sulfur atom in place of the oxygen; important in biochemical reactions.
-
Phosphoryl: Involves a phosphorus atom bonded to oxygen atoms, key in energy transfer processes.
-
Phosphoanhydride: Characterized by the bond between two phosphate groups, significant in ATP and energy metabolism.
