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).

What is the general formula of the homologous series of alkyne and alcohol?
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.
With which homologous series does cyclohexane share its general formula?

Which homologous series is octane in?
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.
Why are alkanes homologous series?
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.
Why alkanes form homologous series?
Alkanes form a homologous series because they share a common general formula, CₙH₂ₙ₊₂, where "n" is the number of carbon atoms. Each successive alkane differs from the previous one by a -CH₂- unit, leading to a gradual change in physical and chemical properties. This consistent pattern in structure and reactivity allows for systematic classification and comparison of alkanes within the series. Additionally, members of the series exhibit similar chemical behaviors due to their analogous functional groups.

Name the homologous series to which propene belongs?
Ester
Why do these substance all belong to the same homologous series?
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.
Which homologous series would you find functional group 3?
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.
Which hydrocarbon is a member of the series with the general formula cnh2n -2?
The hydrocarbon that fits the general formula CnH2n-2 is an alkyne. Alkynes are unsaturated hydrocarbons with a carbon-carbon triple bond.
Chracteristics of homologous series?

Which homologous series is octane in?
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.
What is homologous series in chemistry?
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.
In which group could the hydrocarbons all belong to the same homologous series?
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.
