What differentiates alicyclic hydrocarbons from aromatic hydrocarbons?
What differentiates alicyclic hydrocarbons from aromatic hydrocarbons?
Alicyclic hydrocarbons do not contain a benzene ring, whereas aromatic hydrocarbons do contain a benzene ring.
List the IUPAC name for a hydrocarbon with 5 carbon atoms.
List the IUPAC name for a hydrocarbon with 5 carbon atoms.
The IUPAC name is Pent.
Explain the significance of the general formula in a homologous series.
Explain the significance of the general formula in a homologous series.
The general formula allows for the prediction of the structure and chemical properties of compounds in the series, as each member differs by a -CH2 group.

Study Notes
Hydrocarbons
- Hydrocarbons are classified by structure:
- Straight chain: Propane, butane, etc.
- Branched chain: Iso-butane, iso-pentane, etc.
- Cyclic: Cyclohexane, benzene, etc.
- Closed chain: Alicyclic hydrocarbons (no benzene rings) and aromatic hydrocarbons (with benzene rings).
IUPAC Nomenclature
- IUPAC names have two parts:
- Word root: Number of carbons in the longest carbon chain (Meth, Eth, Prop, But, Pent, Hex, Hept, Oct, Non, Dec).
- Suffix: Determined by the type of carbon-carbon bond. Single bond = -ane, double bond = -ene, triple bond = -yne
Types of Formulas
- Molecular formula: Shows the actual number of each type of atom.
- Structural formula: Shows the arrangement of atoms.
- Condensed formula: A shortened form of the structural formula.
Functional Groups
- Functional groups are heteroatoms or groups of atoms which make carbon compounds reactive and determine their properties
- Examples:
- Halo (Chloro/Bromo/lodo)
- Alcohol
- Aldehyde
- Ketone
- Carboxylic acid
- These groups can be identified by the prefix/suffix they are assigned in naming a molecule.
- These groups change how a molecule functions.
Homologous Series
- A series of organic compounds in which each succeeding member differs from the previous by—CH2 or 14 a.m.u.
- Members' molecular formulas can be derived from a general formula.
- Physical properties change as the molecular mass increases, but chemical properties (determined by functional groups) remain similar throughout the series.
Benzene
- Aromatic hydrocarbon with the molecular formula C₆H₆.
- Has alternating carbon-carbon single and double bonds.
- Can be represented in a circle-bond structure.
