Study Notes
Organic Chemistry
Fundamentals of Organic Chemistry
- Definition: Study of carbon-containing compounds and their properties.
- Key Elements: Primarily carbon (C), hydrogen (H), oxygen (O), nitrogen (N), sulfur (S), phosphorus (P).
-
Functional Groups: Specific groups of atoms that determine the characteristics of organic compounds.
- Examples: Alcohols (-OH), Carboxylic acids (-COOH), Aldehydes (-CHO), Amines (-NH2).
Classification of Organic Compounds
-
Aliphatic Compounds
- Open chain (branched or straight).
- Types:
- Alkanes: Saturated hydrocarbons (C-C single bonds).
- Alkenes: Unsaturated (C=C double bonds).
- Alkynes: Unsaturated (C≡C triple bonds).
-
Aromatic Compounds
- Contain benzene rings.
- Follow Huckel's rule (4n + 2 π electrons).
Isomerism
- Structural Isomers: Different arrangements of atoms (e.g., butane and isobutane).
-
Stereoisomers: Same structural formula but different spatial arrangement.
- Types:
- Geometric (cis/trans) isomerism.
- Optical isomerism (enantiomers).
- Types:
Nomenclature
-
IUPAC Naming: Systematic way to name organic compounds.
- Base name derived from the longest carbon chain.
- Use prefixes/suffixes based on functional groups.
Reactions in Organic Chemistry
-
Types of Reactions:
- Addition Reactions: Atoms are added to unsaturated compounds.
- Elimination Reactions: Atoms are removed from a molecule.
- Substitution Reactions: An atom or group replaces another atom or group.
- Rearrangement Reactions: Atoms in a molecule are rearranged to form a new product.
Key Concepts
- Hybridization: Mixing of atomic orbitals to form new hybrid orbitals (sp, sp², sp³).
- Resonance: Delocalization of electrons in molecules with conjugated systems; stability through resonance structures.
-
Reaction Mechanisms: Step-by-step sequence of events that describes how reactants turn into products.
- Includes intermediates and transition states.
Applications of Organic Chemistry
- Pharmaceuticals: Design and synthesis of drug molecules.
- Biochemistry: Study of organic compounds in biological systems.
- Materials Science: Development of polymers, plastics, and nanomaterials.
Safety in Organic Chemistry
- Awareness of hazards associated with organic chemicals.
- Proper use of personal protective equipment (PPE) and lab safety protocols.

Classification of Organic Compounds
-
Aliphatic Compounds: Open chain structures, branched or straight. Includes:
- Alkanes: Only single bonds between C atoms (saturated).
- Alkenes: Contain at least one double bond between C atoms (unsaturated).
- Alkynes: Contain at least one triple bond between C atoms (unsaturated).
- Aromatic Compounds: Contain benzene rings, which follow Huckel's rule (4n + 2 π electrons).
Isomerism
- Structural Isomers: Same molecular formula but different arrangements of atoms, for example butane and isobutane.
-
Stereoisomers: Same structural formula but different spatial arrangements.
- Geometric (cis/trans) Isomerism: Different arrangement of atoms around a double bond.
- Optical Isomerism (enantiomers): Mirror images that cannot be superimposed.
Nomenclature
- IUPAC Naming: Systematic approach to naming organic compounds based on longest carbon chain and functional groups.
Reactions in Organic Chemistry
- Addition Reactions: Atoms are added to an unsaturated compound.
- Elimination Reactions: Atoms are removed from a molecule.
- Substitution Reactions: An atom or group is replaced by another atom or group.
- Rearrangement Reactions: Atoms within a molecule are rearranged to form a new product.
Key Concepts
- Hybridization: Atomic orbitals mix to form new hybrid orbitals (sp, sp², sp³) influencing molecular shape and bonding.
- Resonance: Electron delocalization in molecules with conjugated systems, leading to increased stability.
- Reaction Mechanisms: Step-by-step description of how reactants transform into products, including intermediates and transition states.
Applications of Organic Chemistry
- Pharmaceuticals: Development and synthesis of drug molecules.
- Biochemistry: Study of organic compounds in biological systems.
- Materials Science: Production of polymers, plastics, and nanomaterials.
Safety in Organic Chemistry
- Essential to be aware of hazards associated with organic chemicals and follow lab safety protocols, using appropriate personal protective equipment (PPE).
