Overview
Carbon is one of the most important and versatile elements on Earth. Despite making up only 0.02% of Earth's crust and 0.03% of the atmosphere, carbon forms the basis of all living organisms and countless compounds used in daily life. This chapter explores why carbon is so special, how it bonds with
Key Concepts
Covalent bonds form when atoms share
Covalent bonds form when atoms share pairs of electrons to achieve noble gas configuration. Unlike ionic bonds that transfer electrons, covalent bonds
Allotropes are different forms of
Allotropes are different forms of the same element with different physical properties but similar chemical properties. Carbon has several important al
Catenation is carbon's unique ability
Catenation is carbon's unique ability to form strong bonds with other carbon atoms, creating long chains, branched chains, and ring structures. This p
Saturated compounds contain only single bonds
Saturated compounds contain only single bonds between carbon atoms (like alkanes: methane CH₄, ethane C₂H₆, propane C₃H₈). They follow the general for
Structural isomers are compounds with
Structural isomers are compounds with the same molecular formula but different structural arrangements. For example, butane (C₄H₁₀) has two isomers: s
