Study Notes
Organic Compounds
- Composed primarily of carbon atoms.
- Characterized as inflammable and highly volatile.
- Exist in various states: gas, liquid, and solid.
- Typically insoluble in water.
- Predominantly contain carbon-to-hydrogen bonds.
- Commonly found in living organisms.
- Examples include carbohydrates and lipids.
Inorganic Compounds
- Lack carbon atoms in their structure.
- Non-volatile and not inflammable.
- Typically found in solid state.
- Generally insoluble in water.
- Predominantly occur in non-living organisms.
Organic Chemistry
- Defined as the study of carbon-based compounds.
- Valence electrons are responsible for bonding.
- Carbon can form four covalent bonds with other carbons or non-metals.
Hydrocarbons
- Organic compounds consisting solely of carbon and hydrogen.
Isomerism
- Refers to compounds with the same chemical formula but different structural configurations.
Types of Organic Compounds
- Aliphatic: Carbon chains that can be linear or branched.
- Aromatic: Compounds containing aromatic rings.
Alkanes
- Saturated hydrocarbons with only single carbon-carbon bonds.
- Represent the simplest form of hydrocarbons.
Alkenes
- Unsaturated hydrocarbons characterized by carbon-carbon double bonds.
Alkynes
- Unsaturated hydrocarbons identified by carbon-carbon triple bonds.
- Known as the acetylene series.
Alkyl Groups
- Derived from alkanes, having one less hydrogen atom.
- Also referred to as haloalkanes when hydrogen is replaced by halogen atoms.
Hydrocarbon Derivatives
- Without Carbonyl: Includes halocarbons, alcohols, ethers, amines.
- With Carbonyl: Encompasses aldehydes, ketones, carboxylic acids, esters, and amides.
Functional Groups
- Specific groups of atoms within molecules that determine chemical reactivity and properties.
Organic Compounds
- Composed primarily of carbon atoms, which are covalently bonded to hydrogen and sometimes other elements.
- Generally inflammable, highly volatile, and exist as gases, liquids, or solids.
- Usually insoluble in water but soluble in organic solvents.
- Important examples include carbohydrates and lipids.
- Formed from hydrocarbons, which only contain carbon and hydrogen.
- Exhibit isomerism, where compounds share the same molecular formula but differ in structure.
Inorganic Compounds
- Lack carbon atoms, making them distinct from organic compounds.
- Non-volatile and non-inflammable; exist primarily in solid state.
- Soluble in water, with a few exceptions; generally remain insoluble in organic solvents.
- Predominantly found in non-living entities.
Organic Chemistry
- Focuses on the study of carbon and its compounds.
- Organic compounds are integral to all living organisms, derived mainly from hydrocarbons.
Hydrocarbons
- Categorized into three types based on bonding: alkanes (single bonds), alkenes (double bonds), and alkynes (triple bonds).
- Aliphatic hydrocarbons are further divided into straight or branched chains and do not possess benzene groups.
- Aromatic hydrocarbons contain benzene rings or derivatives.
Functional Groups
- Groups of atoms that determine the chemical behavior of organic compounds.
- Types of functional groups include alcohols, ethers, amines, aldehydes, ketones, carboxylic acids, esters, and amides.
Characteristics of Organic Compounds
- Combust readily to produce carbon dioxide and water.
- Generally less stable when exposed to heat compared to inorganic compounds.
- Form complex molecules, demonstrating varied reactivity.
- Presence of isomers allows multiple structural forms for the same molecular formula.
Types of Hydrocarbons
- Alkanes: Saturated hydrocarbons with single carbon-carbon bonds. General formula: CnH2n+2.
- Alkenes: Unsaturated hydrocarbons with carbon-carbon double bonds.
- Alkynes: Unsaturated hydrocarbons containing carbon-carbon triple bonds.
Aromatic Compounds
- Benzene: The fundamental aromatic compound.
- Naphthalene: Composed of fused benzene rings, known for its distinctive aroma.
- Anthracene: Contains three fused benzene rings, featured in rigid structures.
Molecular Geometry
- Explores three-dimensional shapes of organic molecules and their influence on properties.
- Recognizes the significance of bonding patterns in forming stable compounds through covalent, ionic, and hydrogen bonds.
