Homologous Series starts at 10 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Homologous Series. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

See sample questions for grade 11

Describe one way in which homologous series are useful in organic chemistry.

Describe the trend in solubility of alcohols in water as the number of carbon atoms increases.

Explain why members of a homologous series have similar chemical properties.

Explain why the melting point of alkanes increases with increasing molecular mass.

If the molecular formula of an alcohol is C₃H₇OH, what is the molecular formula of the next member in the series?

If the molecular formula of an alkane is C₅H₁₂, what is the molecular formula of the next member in the series?

Name the homologous series to which the compound CH₃CH₂OH belongs.

State one reason why the boiling point increases as you go higher in a homologous series.

State the general formula for the homologous series of primary amines.

What is a homologous series in organic chemistry?

A student claims that the compound C₄H₁₀O can belong to more than one homologous series. Justify this statement with examples.

Calculate the molecular mass of the third member of the alkene homologous series.

Describe how the presence of a functional group in a homologous series influences the chemical reactivity of its members.

Explain why the difference in boiling points between consecutive members of a homologous series becomes less pronounced as the number of carbon atoms increases.

Given the general formula for alkanols (alcohols) is C_nH_2n+1OH, derive the molecular formula for the fifth member of this homologous series and name the compound.
