Organic Chemistry

Definition:
- Branch of chemistry that studies the structure, properties, composition, reactions, and preparation of carbon-containing compounds.
Key Concepts:
- Carbon Compounds: Primarily composed of carbon (C), often in combination with hydrogen (H), oxygen (O), nitrogen (N), sulfur (S), and halogens (F, Cl, Br, I).
- Functional Groups: Specific groups of atoms within molecules that determine the chemical reactivity and properties.
  - Examples: Hydroxyl (-OH), Carboxyl (-COOH), Amino (-NH2), Carbonyl (C=O).
Types of Organic Compounds:
- Aliphatic Compounds: Contain carbon in straight or branched chains. (e.g., alkanes, alkenes, alkynes)
- Aromatic Compounds: Contain a benzene ring or similar structure.
Isomerism:
- Structural Isomers: Differ in the connectivity of atoms.
- Stereoisomers: Same connectivity but different spatial arrangement.
  - Geometric Isomers: Different spatial arrangement around a double bond (cis/trans).
  - Enantiomers: Non-superimposable mirror images (optical isomers).
Nomenclature:
- Use the IUPAC (International Union of Pure and Applied Chemistry) system for naming organic compounds.
- Based on longest carbon chain, functional groups, and position of substituents.
Reactions:
- Addition Reactions: Atoms or groups are added to the double or triple bond.
- Substitution Reactions: An atom or group in a molecule is replaced by another atom or group.
- Elimination Reactions: Atoms or groups are removed, forming double or triple bonds.
- Rearrangement Reactions: Molecules undergo structural changes.
Key Reagents:
- Acids and Bases: Influence reaction pathways and product formation.
- Catalysts: Substances that increase reaction rates without being consumed.
Polymers:
- Large molecules formed by the repeating structural units (monomers), e.g., polyethylene, proteins.
Applications:
- Pharmaceuticals, agrochemicals, plastics, synthesis of natural products.
Spectroscopy and Analysis:
- Techniques used to identify organic substances include NMR (Nuclear Magnetic Resonance), IR (Infrared Spectroscopy), and UV-Vis (Ultraviolet-Visible Spectroscopy).

Understanding these core aspects of organic chemistry provides a foundation for exploring more complex concepts in the field.

Organic Chemistry

Branch of chemistry focusing on carbon-containing compounds.
Carbon is the backbone of organic molecules, often combined with hydrogen, oxygen, nitrogen, sulfur, and halogens.
Functional Groups: Specific groups of atoms that define the chemical reactivity and properties of organic compounds.
- Examples: Hydroxyl (-OH), Carboxyl (-COOH), Amino (-NH2), Carbonyl (C=O)
Types of Organic Compounds:
- Aliphatic Compounds: Contain carbon in straight or branched chains (e.g., alkanes, alkenes, alkynes).
- Aromatic Compounds: Contain a benzene ring or similar structure.
Isomerism: Molecules with the same molecular formula but different arrangements of atoms.
- Structural Isomers: Differ in the connectivity of atoms.
- Stereoisomers: Have the same connectivity but differ in spatial arrangement.
  - Geometric Isomers: Differ in the spatial arrangement around a double bond (cis/trans).
  - Enantiomers: Non-superimposable mirror images (optical isomers).
Nomenclature: IUPAC (International Union of Pure and Applied Chemistry) system used to name organic compounds based on the longest carbon chain, functional groups, and substituent positions.
Reactions:
- Addition Reactions: Atoms or groups are added to double or triple bonds.
- Substitution Reactions: An atom or group in a molecule is replaced by another atom or group.
- Elimination Reactions: Atoms or groups are removed, forming double or triple bonds.
- Rearrangement Reactions: Molecules undergo structural changes.
Key Reagents:
- Acids and Bases: Influence reaction pathways and product formation.
- Catalysts: Substances that increase reaction rates without being consumed.
Polymers: Large molecules formed by repeating structural units (monomers) and are prevalent in everyday materials like plastics and proteins.
Applications: Organic chemistry is essential in pharmaceuticals, agrochemicals, plastics, and the synthesis of natural products.
Spectroscopy and Analysis: Techniques like NMR, IR, and UV-Vis are vital for identifying and characterizing organic substances.
