The general formula for the alkyne homologous series is CₙH₂ₙ₋₂, where n represents the number of carbon atoms in the molecule. Alkynes are characterized by at least one triple bond between carbon atoms. This formula illustrates that for each additional carbon atom, two fewer hydrogen atoms are present compared to alkanes (CₙH₂ₙ₊₂) and alkenes (CₙH₂ₙ).
The general formula for alkynes is CnH2n-2, where n represents the number of carbon atoms in the alkyne molecule. For alcohols, the general formula is CnH2n+2O, where n represents the number of carbon atoms and O represents the oxygen atom.
Cyclohexane shares its general formula with the cycloalkanes homologous series, which is CnH2n.
Octane belongs to the homologous series of alkanes, which are saturated hydrocarbons characterized by single bonds between carbon atoms. The general formula for alkanes is CₙH₂ₙ₊₂, where "n" represents the number of carbon atoms. Octane specifically has eight carbon atoms, with the molecular formula C₈H₁₈.
Alkanes are considered a homologous series because they share the same general formula (CnH2n+2) and have similar chemical properties due to a repeating pattern of carbon and hydrogen atoms in their structure. The physical and chemical properties of alkanes vary gradually as the number of carbon atoms increases, showing a clear trend within the series.
Toluene belongs to the homologous series of aromatic hydrocarbons, specifically the alkylbenzenes. It is characterized by a benzene ring with a methyl group attached, making its chemical formula C7H8. This series includes other compounds like xylene and ethylbenzene, which have varying alkyl group substitutions on the benzene ring.
The general formula for alkynes is CnH2n-2, where n represents the number of carbon atoms in the alkyne molecule. For alcohols, the general formula is CnH2n+2O, where n represents the number of carbon atoms and O represents the oxygen atom.
Cyclohexane shares its general formula with the cycloalkanes homologous series, which is CnH2n.

A homologous series is a family of organic compounds that: *have the same general formula. *have similar chemical properties and *show a gradual increase in physical properties such as melting and boiling point.
Ester
Substances belong to the same homologous series if they have similar chemical structures with a repeating functional group or molecular formula pattern. This commonality results in analogous physical and chemical properties among the substances in the series, making them part of the same homologous series.
The functional group of 3 would be alcohol, which is part of the homologous series known as alcohols. These compounds have the general formula R-OH, where R represents a hydrocarbon chain.
The hydrocarbon that fits the general formula CnH2n-2 is an alkyne. Alkynes are unsaturated hydrocarbons with a carbon-carbon triple bond.

Octane belongs to the homologous series of alkanes, which are saturated hydrocarbons characterized by single bonds between carbon atoms. The general formula for alkanes is CₙH₂ₙ₊₂, where "n" represents the number of carbon atoms. Octane specifically has eight carbon atoms, with the molecular formula C₈H₁₈.
This is part of organic chemistry. Homologous Series: is a series of compounds with the SAME GENERAL FORMULA, SIMILAR CHEMICAL PROPERTIES, and a GRADUATION IN PHYSICAL PROPERTIES, where each member differs from the previous member by a CH2 group. For example: ALKANES: General formula is C(n)H(2n+2) eg. C2H6 or C3H8 or C4H10. All of these are saturated molecules, so they contain the maximum number of hydrogen atoms per molecule, ie. all bonds are single and there are no unused electron pairs. This means that these will not be able to undergo addition reactions because there are no free electron pairs to bond to. Therefore, alkanes have SIMILAR CHEMICAL PROPERTIES. Also, no alkane is polar. Alkanes have a GRADUATION IN PHYSICAL PROPERTIES because as there are more CH2 groups, the molecule's mass and size increases, hence the strength of the acting intermolecular forces, the Van der Waal's forces is increasing therefore the bigger the molecule, the stronger the intermolecular forces, therefore the higher the boiling point.
All hydrocarbons belonging to the same homologous series will share a similar general formula and exhibit a consistent progression in physical properties (such as boiling points and melting points) as the number of carbon atoms increases. Examples of hydrocarbons that could belong to the same homologous series include alkanes, alkenes, and alkynes.
