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.

What are the main homologous series for organic compounds?
All the families of organic compounds exist as a homologous series (A series having a difference of 'CH2' unit between two consecutive members) the main homologous series-es are Alkanes, Alkenes, Alcohols and Carboxylic acids (Fatty acids).
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 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.
What are the 3 series in saturated hydrocarbons?
These 3 series of saturated hydrocarbon are: linear alkanes, branched alkanes, cycloalkanes.
What is the general formula for the alkyne homologous series?
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).

Which compound is a member of the same homologous series as C3H8?
C4H10, butane, is a member of the same homologous series as C3H8, propane. Both are alkanes with consecutive carbon chain lengths and differ by a CH2 unit.
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.
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.
What is homologous series give example give an example of positional isomer?
A homologous series is a family of organic compounds with similar chemical properties due to the presence of the same functional group and a recurring structural unit. An example is the alkanes series, where each member differs by a CH2 group. An example of positional isomer is 1-propanol and 2-propanol.
What is homologous series of organic compounds?
Homologous series of organic compounds are families of compounds that have similar chemical properties due to having the same functional group and a repeating pattern of carbon atoms. Members of the series will have the same general formula and exhibit a trend in physical properties as the number of carbon atoms increases. Examples include alkanes, alkenes, and alkynes.
What are the 3 series in saturated hydrocarbons?
These 3 series of saturated hydrocarbon are: linear alkanes, branched alkanes, cycloalkanes.
Which series contains only substances with single covalent bonds?
The series containing only substances with single covalent bonds is the hydrocarbons called alkanes. Alkanes are saturated hydrocarbons having only single bonds between carbon atoms.
With which homologous series does cyclohexane share its general formula?
Cyclohexane shares its general formula with the cycloalkanes homologous series, which is CnH2n.
Name the homologous series to which propene belongs?
Ester
Why does flammability of alkenes decrease?
the flammability of alkanes decreases as the hydrocarbon chains increase in length their evapouration rates decrease as longer chained molecules have higher boling points so temperatures must be high for them to evaporate therefore there is no fumes or vapours for longer chained alkanes at room temp like nonane and so on these hydrocarbons need higher temp to produce vapours n therefore will not burn with just a match
What is a homologous substance?
A homologous substance refers to a series of compounds that share a similar structure and chemical properties but differ by a systematic increment, typically in the number of carbon and hydrogen atoms. These compounds often belong to the same functional group and exhibit a gradual change in physical properties, such as boiling or melting points, with each successive member of the series. Common examples include the alkanes, where each successive member increases by a CH2 unit.
