Study Notes
Alcohol
- Contains an -OH (hydroxyl) group bonded to a tetrahedral carbon atom
- Classified as primary (1°), secondary (2°), and tertiary (3°) based on the number of carbon atoms bonded to the carbon bearing the -OH group
Aldehyde
- Contains a carbonyl group (C=O) bonded to a hydrogen
- Has a -CHO group
Amide
- A functional derivative of a carboxylic acid
- An amino group replaces the -OH of the carboxyl group
Amine
- Organic compound where one, two, or three hydrogens of ammonia are replaced by carbon groups
- RNH₂, R₂NH, or R₃N, where R represents a carbon group
Amine Classification
- Primary (1°), secondary (2°), and tertiary (3°)
- Based on the number of carbon groups bonded to the nitrogen atom of the amino group
Amino Group
- A nitrogen atom bonded to one, two, or three R groups
- RNH₂, R₂NH, or R₃N, where R represents a carbon group
Carbonyl Group
- A C=O group
Carboxyl
- Carbonyl + hydroxyl group
- A -COOH group
Carboxylic Acid
- Contains a -COOH group
Carboxylic Ester
- A derivative of a carboxylic acid
- A carbon group replaces the H of the carboxyl group
- -COOR or -CO₂R
Condensed Structural Formula
- A shorthand method for writing organic structures
- Hydrogens are grouped with the atom they are attached to
Functional Group
- The group of atoms that gives a compound its identity
- Group of atoms within a molecule that shows a characteristic set of predictable physical and chemical behaviors
Hydroxyl (-OH) group
- An -OH group bonded to a tetrahedral carbon atom
Ketone
- Contains a carbonyl group (C=O) bonded to two carbon groups
Organic Chemistry
- The study of carbon compounds
Functional Group Summary
- Hydroxyl Group: A defining feature of alcohols, this group consists of an oxygen atom attached to a hydrogen atom (-OH).
- Carbonyl Group: A crucial component in aldehydes and ketones, this group features a carbon atom double-bonded to an oxygen atom (C=O).
- Carboxyl Group: Found in carboxylic acids, this group is a combination of a carbonyl and a hydroxyl group (-COOH), giving the compound acidic properties.
- Amino Group: Characterized by a nitrogen atom connected to one, two, or three carbon groups (RNH2, R2NH, or R3N). These are key building blocks in amino acids, proteins, and other biological molecules.
Alcohol Classification
- Primary alcohols (1°): Possess one carbon atom attached to the carbon bearing the -OH group.
- Secondary alcohols (2°): Have two carbon atoms bonded to the carbon bearing the -OH group.
- Tertiary alcohols (3°): Feature three carbon atoms connected to the carbon bearing the -OH group.
Aldehyde & Ketone Differentiation
- Aldehydes: Contain a carbonyl group bonded to a hydrogen atom (-CHO).
- Ketones: Feature a carbonyl group linked to two carbon groups.
Amide & Amine Summary
- Amides: Derived from carboxylic acids by replacing the -OH group with an amino group (RCONH2). They are formed by a reaction between a carboxylic acid and an amine.
- Amines: Organic compounds containing a nitrogen atom bonded to one, two, or three carbon groups (RNH2, R2NH, or R3N).
Amine Classification
- Primary amines (1°): Possess one carbon group attached to the nitrogen atom.
- Secondary amines (2°): Have two carbon groups bonded to the nitrogen atom.
- Tertiary amines (3°): Feature three carbon groups connected to the nitrogen atom.
Ester & Carboxylic Acid Relationship
- Carboxylic Esters: Derived from carboxylic acids by replacing the hydrogen of the carboxyl group with a carbon group (-COOR, -CO2R).
Organic Chemistry & Condensed Structural Formulas
- Organic chemistry: Focuses on the study of carbon compounds.
- Condensed Structural Formulas: A shorthand method for expressing organic structures where hydrogens are bundled with the atoms they are attached to.
