Overview
Carbon is one of the most important elements on Earth, forming the backbone of all living organisms and countless useful compounds. Despite constituting only 0.02% of Earth's crust and 0.03% of atmospheric CO₂, carbon's unique properties make it essential for life and industry. This chapter explores
Key Concepts
Carbon has 4 valence electrons
Carbon has 4 valence electrons and needs 4 more to complete its octet. Instead of gaining or losing electrons (which would require too much energy), c
Carbon atoms can arrange themselves
Carbon atoms can arrange themselves in different ways to form diamond (3D rigid structure with each carbon bonded to 4 others), graphite (hexagonal la
Catenation is carbon's unique ability
Catenation is carbon's unique ability to form long chains by bonding with other carbon atoms. Tetravalency means carbon can form 4 bonds. Together, th
Saturated compounds have only single bonds
Saturated compounds have only single bonds between carbon atoms (like alkanes CₙH₂ₙ₊₂), while unsaturated compounds have double or triple bonds (alken
Functional groups are atoms or groups
Functional groups are atoms or groups of atoms that give specific properties to compounds (like -OH in alcohols, -COOH in acids). A homologous series
