Study Notes

Characteristics of Covalent Bond Formation

Involves the sharing of electron pairs between atoms.
Leads to the formation of molecules with different geometries and bond angles.
Energy is released when covalent bonds form, making them stable structures.
Common in non-metal atoms that tend to have similar electronegativities.

Versatility of Carbon in Organic Chemistry

Carbon has four valence electrons, allowing it to form four covalent bonds.
This enables the creation of a diverse range of compounds, including chains, rings, and complex structures.
Carbon's ability to form stable bonds with itself and different elements contributes to the vast array of organic molecules.

Allotropes of Carbon

Common allotropes include diamond, graphite, fullerene, and graphene.
Not all carbon forms are classified as allotropes; for example, carbon black is not considered an allotrope of carbon.

Carbon Nomenclature and Prefixes

The prefix "prop-" is used to denote a molecule with three carbon atoms in organic chemistry.
Nomenclature is essential for systematically naming and identifying organic compounds.

Structures of Carbon Allotropes

Carbon allotropes differ in their atomic arrangements leading to distinct physical and chemical properties.
Diamond has a tetrahedral structure providing high rigidity and excellent hardness.
Graphite consists of layered sheets that allow for conductivity and lubricating properties.
