Study Notes
Introduction to Organic Chemistry
- Organic chemistry is the study of compounds containing carbon, excluding CO2, CO, CO32-, CN, and HCO3-.
- Organic compounds typically contain carbon and hydrogen, but also may contain other elements like nitrogen, oxygen, halogens, phosphorus, and sulfur.
- Inorganic compounds lack a carbon-to-hydrogen bond and often contain metals.
Uniqueness of Carbon
- Carbon is the 6th element in the periodic table.
- Carbon commonly forms the backbone of molecules in living organisms.
- Carbon can form a combination of single, double, and triple covalent bonds.
- Carbon's ability to bond with itself (catenation) allows a vast array of molecule structures.
Chemical Bonds
- Chemical bonds hold molecules together, resulting from the interaction of electrons in atomic orbitals.
- Two main types of chemical bonds:
- Intramolecular bonds: Bonds within a single molecule.
- Intermolecular bonds: Bonds between two or more molecules.
- Types of intramolecular bonds:
- Ionic bonds: Transfer of electrons between a metal and a nonmetal.
- Covalent bonds: Sharing of electrons between nonmetals.
- Polar covalent bonds: Unequal sharing of electrons.
- Nonpolar covalent bonds: Equal sharing of electrons.
- Types of intermolecular bonds:
- Hydrogen bonds: A strong dipole-dipole interaction between hydrogen and a highly electronegative atom (N, O, F).
- Ion-dipole bonds: A bond between an ion and a polar molecule.
- Dipole-dipole bonds: A bond between two polar molecules.
- London dispersion forces: Weak attractive forces between nonpolar molecules.
Valence Bond Theory
- Valence bond theory explains how bonds form by sharing electrons in overlapping atomic orbitals to form molecular orbitals.
- Sigma (σ) bonds form by head-on overlap of orbitals, while pi (π) bonds form by sideways overlap of p orbitals.
- Hybridization describes the mixing of atomic orbitals to form new orbitals with specific shapes and orientations.
- sp3 hybridization: 4 hybridized orbitals, 4 sigma bonds, 0 pi bonds
- sp2 hybridization: 3 hybridized orbitals, 3 sigma bonds, 1 pi bond
- sp hybridization: 2 hybridized orbitals, 2 sigma bonds, 2 pi bonds.
Resonance
- Resonance describes delocalized electrons in molecules or polyatomic ions that cannot be represented by a single Lewis structure.
- Equivalent Lewis structures are called resonance structures, linked by double-headed arrows.
- Resonance structures differ only in the position of pi bonds or nonbonding electrons.
- The resonance hybrid is more stable than any individual resonance form.
Lewis Structure
- Lewis structures visualize the arrangement of valence electrons around atoms in a molecule.
- Electrons are represented as dots or lines between atoms to show bonding.
- Skeletal structures depict the arrangement of atoms in a molecule.
- Formal charges are calculated to help determine the most likely resonance structure by considering the electronegativity of the atoms.
Periodic Table
- The periodic table organizes chemical elements by atomic number and properties.
- Valence electrons in an element's outermost shell determine how an atom reacts in a chemical reaction.
Organic Chemistry: History
- Jöns Jacob Berzelius coined the term "organic chemistry" in 1806.
- The "vital force theory" proposed that organic compounds could only be formed by living organisms.
- Friedrich Wöhler disproved the vital force theory in 1828 by synthesizing urea, a biological compound, in a laboratory.
Molecular Geometry
- Molecular geometry describes the three-dimensional arrangement of atoms in a molecule and affects the molecule's properties like polarity.
Polarity of Molecules
- Molecular polarity arises from the unequal sharing of electrons in polar covalent bonds and the molecular geometry.
