Organic Chemistry Quiz: Part 2
An interactive quiz on Aliphatic, Alicyclic, and Aromatic Hydrocarbons.
Fundamental Concepts Review
Aliphatic vs. Alicyclic: Aliphatic hydrocarbons feature open-chain structures (e.g., hexane). Alicyclic hydrocarbons contain carbon atoms arranged in a non-aromatic ring (e.g., cyclohexane).
Aromatic Hydrocarbons: This special class of cyclic compounds, exemplified by benzene ($C_6H_6$), exhibits unique stability due to a delocalized $\pi$ electron system. This property, called aromaticity, leads them to favor substitution over addition reactions.
General Formulas: Homologous series like alkanes can be described by general formulas. For non-cyclic alkanes, the formula is $C_nH_{2n+2}$, while for alkenes and cycloalkanes it is $C_nH_{2n}$.
