Study Notes
Functional Groups and Organic Compound Naming
- Aldehydes end in "-al" and feature a terminal carbonyl group.
- Ketones have an intermediate carbonyl and end in "-one".
- Alcohols are identified by the suffix "-ol" and have a hydroxide branch, starting with "hydroxy-" if combined with another functional group.
- Carboxylic acids end with "-oic" and "acid," possessing both a terminal carbonyl and hydroxide branch on the same carbon.
Amine and Amide Characteristics
- Amines conclude with "-amine" and contain a terminal nitrogen group, beginning with "amino-" when paired with another functional group.
- Amides are marked by the suffix "-amide," having a terminal nitrogen and carbonyl branch on the same carbon.
Ester and Ether Formation
- Esters result from the reaction between an alcohol and a carboxylic acid, characterized by an intermediate carbonyl and an oxygen atom, changing the alcohol name to "-yl" and the acid name to "-oate."
- Ethers split into two parts, with the shorter chain ending in "-oxy" and the longer retaining the original chain name.
Halogenoalkane and Carbon Chain Naming
- Halogenoalkanes are named by the combination of the alkane name with the functional group name.
- Common carbon chains include methane (1 carbon), ethane (2 carbons), propane (3), butane (4), pentane (5), and hexane (6).
Bond Types in Carbon Chains
- "-ane" indicates only single bonds, while "-ene" signifies at least one double bond, and "-yne" denotes a triple bond.
Alkyl Naming Conventions
- Alkyl groups are named by replacing "-ane" with "-yl".
Cycloalkanes
- The prefix "cyclo-" denotes that the carbon forms a ring structure.
IUPAC Naming Steps
- Identify the longest carbon chain and assign the appropriate suffix for bond types (ane, ene, yne).
- Number functional groups to achieve the lowest possible numbers for branching.
- Use numerical prefixes for multiple functional groups.
- Organize functional groups in alphabetical order, disregarding numerical prefixes, with the chain name at the end.
- If there’s a hydrocarbon within the functional group, the name ends with "-yl".
Naming Hierarchy
- Prioritize naming based on functional group importance: Aldehydes, Carboxylic Acids, and Amides first; followed by Ketones; then double bonds; and lastly Alkyls, Halogenoalkanes, and Alcohols.
