Study Notes

Organic Chemistry

Definition: Study of carbon-containing compounds and their properties, structures, reactions, and synthesis.
Key Concepts:
- Functional Groups: Specific groups of atoms that determine the chemical properties of compounds (e.g., -OH, -COOH, -NH2).
- Isomerism: Compounds with the same molecular formula but different structures (e.g., structural isomers, stereoisomers).
- Reactions:
  - Addition Reactions: Two or more reactants form a single product (e.g., alkenes + H2).
  - Elimination Reactions: Removal of a small molecule from a larger one (e.g., dehydration of alcohols).
  - Substitution Reactions: One atom or group is replaced by another (e.g., alkyl halides).
- Types of Organic Compounds:
  - Aliphatic Compounds: Non-aromatic hydrocarbons, including alkanes, alkenes, and alkynes.
  - Aromatic Compounds: Compounds containing benzene rings with delocalized pi electrons.

Halogen Derivatives

Definition: Organic compounds containing halogen atoms (F, Cl, Br, I) replacing hydrogen in hydrocarbons.
Types:
- Alkyl Halides: Halogen attached to an alkane (e.g., chloroethane).
- Aryl Halides: Halogen attached to an aromatic ring (e.g., bromobenzene).
Nomenclature:
- Named similarly to alkanes but with halogen prefixes (e.g., chloro-, bromo-, iodo-).
- The longest carbon chain is identified, and the halogen substituents are numbered and named accordingly.
Physical Properties:
- Vary based on the type of halogen and the carbon chain length.
- Generally have higher boiling points than their alkane counterparts due to increased molecular weight and polarizability.
Reactions:
- Nucleophilic Substitution: Halogen can be replaced by a nucleophile (e.g., SN1 and SN2 mechanisms).
- Elimination Reactions: Halogens can be eliminated to form double or triple bonds (e.g., dehydrohalogenation).
- Reduction Reactions: Halogen derivatives can be converted to alkanes (e.g., reduction of alkyl halides).
Applications:
- Used in solvents, pharmaceuticals, and as intermediates in organic synthesis.
Safety:
- Many halogenated compounds can be toxic or harmful to the environment; proper handling and disposal are essential.

Organic Chemistry

The study of carbon-containing compounds including their properties, structures, reactions, and synthesis
Functional groups, specific groups of atoms within molecules, determine chemical properties
Isomerism occurs when compounds have the same molecular formula but different structures, such as structural and stereoisomers
Addition Reactions combine reactants to form one product, like adding hydrogen to alkenes
Elimination Reactions remove small molecules from larger ones, like dehydration of alcohols
Substitution Reactions replace one atom or group with another, such as alkyl halides
Aliphatic Compounds are non-aromatic hydrocarbons including alkanes, alkenes, and alkynes
Aromatic Compounds contain benzene rings with delocalized pi electrons

Halogen Derivatives

Organic compounds containing halogen atoms (F, Cl, Br, I) in place of hydrogen within hydrocarbons
Alkyl Halides have a halogen attached to an alkane, for example, chloroethane
Aryl Halides have a halogen attached to an aromatic ring, for example, bromobenzene
Halogen derivatives are named using prefixes like chloro-, bromo-, iodo-
Physical properties vary based on the type of halogen and the number of carbons in the chain
Halogens increase molecular weight which increases boiling points due to increased polarizability
Nucleophilic Substitution reactions replace a halogen with a nucleophile using SN1 or SN2 mechanisms
Elimination Reactions remove halogens to create double or triple bonds, for example, dehydrohalogenation
Reduction Reactions transform halogen derivatives to alkanes, like reducing alkyl halides
Halogenated compounds are used in solvents, pharmaceuticals, and as intermediates in organic synthesis
Safety: Many halogenated compounds can be toxic and harmful to the environment, proper handling and disposal are essential
