Organic Compounds Containing Oxygen Cheatsheet & Quiz

Definition: Organic compounds containing oxygen possess oxygen atoms in functional groups influencing their chemistry.
Major Classes: Alcohols, Ethers, Aldehydes, Ketones, Carboxylic Acids, Esters.
Alcohols: Contain hydroxyl group (-OH) attached to saturated carbon; general formula \( R-OH \).
Ethers: Contain an oxygen atom bonded to two alkyl or aryl groups; general formula \( R-O-R' \).
Aldehydes and Ketones: Contain carbonyl group (C=O); aldehydes have at least one hydrogen attached, ketones have two carbon groups.
Carboxylic Acids: Contain carboxyl group (-COOH); acidic properties due to resonance-stabilized carboxylate anion.
Esters: Derived from carboxylic acids with an alkoxy group replacing hydrogen; general formula \( R-COO-R' \).
Nomenclature: Named using IUPAC rules with suffixes like -ol, -al, -one, -oic acid, and -ate.
Reactivity: Includes oxidation, reduction, nucleophilic addition and substitution, depending on functional groups.
Importance: Widely present in pharmaceuticals, fragrances, polymers, and biological molecules.

Type	General Formula	Characteristic Functional Group
Alcohol	\( R-OH \)	Hydroxyl group (-OH) on saturated carbon
Ether	\( R-O-R' \)	Oxygen connected between two carbons
Aldehyde	\( R-CHO \)	Carbonyl with at least one hydrogen
Ketone	\( R-CO-R' \)	Carbonyl between two carbons
Carboxylic Acid	\( R-COOH \)	Carboxyl group (-COOH)
Ester	\( R-COO-R' \)	Derived from carboxylic acid and alcohol

Identify Functional Groups: Recognize oxygen-containing groups to predict properties and reactions.

Remember Naming Conventions: Use suffixes and prefixes appropriate to the functional group.

Understand Reactivity: Carbonyl groups are electrophilic; hydroxyl groups participate in hydrogen bonding.

Practice Reactions: Know oxidation, reduction, esterification, and substitution reactions relevant to these groups.

Check Structure: Use molecular formulas and structures to confirm compound class.

Alcohols: Classified as primary, secondary, or tertiary depending on carbon attachment.
Ethers: Generally less reactive; used as solvents due to relative stability.
Aldehydes: More reactive than ketones; oxidizable to carboxylic acids.
Ketones: Resistant to mild oxidation; key in many biochemical pathways.
Carboxylic Acids: Exhibit acidic properties and form salts and esters.
Esters: Often have pleasant odors; formed via esterification between acid and alcohol.
