Study Notes
Functional Groups Overview
- Amino Group (-NH2): Represents amines; acts as a base by picking up H+ ions from the surrounding solution.
- Hydroxyl Group (-OH): Contributes to the chemical properties of molecules; generally associated with alcohols.
Organic Chemistry
- Focuses on carbon-containing compounds, which are often bonded with hydrogen atoms.
- Fundamental to understanding life processes and interactions.
Carbon Diversity
- Carbon's electron configuration allows for versatile bonding, influencing the types of compounds formed.
- Common elements associated with organic compounds include Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N), Sulfur (S), and Phosphorus (P).
Carbon Bonds
- Carbon has 4 valence electrons, enabling it to form 4 covalent bonds.
- This versatility allows for the development of large, complex molecules.
- Single Covalent Bond: Involves sharing one electron; foundational for hydrocarbon structures.
Double Bonds
- Characterized by flat shapes and the sharing of 2 electrons.
- All atoms involved in a double bond lie in the same plane, affecting the molecule's geometry.
Hydrocarbon Chains
- The arrangement of carbon-carbon bonds determines the molecules' shape, impacting flexibility or rigidity.
- Hydrocarbons consist solely of carbon and hydrogen atoms.
Hydrocarbon Properties
- Common in lipids and fats (oils); possess hydrophobic characteristics due to non-polar properties.
- Equal sharing of electrons between carbon and hydrogen leads to noncharge, making them insoluble in water.
Molecular Prefixes and Suffixes
- Prefix: eth indicates compounds with two carbon atoms.
-
Suffix: Identifies types of bonds:
- -ane: denotes single bonds (alkanes).
- -ene: denotes double bonds (alkenes).
- -yne: denotes triple bonds (alkynes).
Isomers
- Definition: Compounds having the same molecular formula but different structures and properties.
- Key to understanding diversity in organic compounds and their functions.
Functional Groups Insight
- Functional groups are specific groupings of atoms that determine the chemical reactivity and characteristics of molecules.
- The presence of a functional group modifies the behavior of the remaining parts of the molecule.
