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.
