Alkenes, Alkynes And Aromatics: Test Your Knowledge! Trivia Quiz

1. CH₄

Alkane

Alkene

Alkyne

Option 4

The correct answer is Alkane because CH4 is the chemical formula for methane, which is the simplest and most basic type of alkane. Alkanes are hydrocarbons that consist of only single bonds between carbon atoms and are saturated with hydrogen atoms. Methane, being a single-bonded hydrocarbon with four hydrogen atoms, fits the definition of an alkane. Alkenes and alkynes, on the other hand, have double and triple bonds between carbon atoms respectively, which is not the case with CH4.

2. Butane

Alkane

Alkene

Alkyne

Butane is an alkane because it is a hydrocarbon with four carbon atoms and has a single bond between each carbon atom. Alkanes are a type of saturated hydrocarbon where all the carbon atoms are bonded to each other with single bonds. They have the general formula CnH2n+2 and are known for their relatively low reactivity. Butane fits this description as it contains only single bonds between its carbon atoms and follows the formula C4H10, making it an alkane.

3. What are aromatic compounds?

Organic compounds

My left toe

Organic compounds that contain benzene rings as part of their structure

Hydrocarbons such as alkanes, alkenes, and alkynes

Aromatic compounds are organic compounds that contain benzene rings as part of their structure. Benzene rings are a specific type of ring structure consisting of six carbon atoms arranged in a hexagonal shape with alternating single and double bonds. Aromatic compounds are known for their distinct smell and are often used in perfumes and fragrances. They have unique chemical properties and are widely studied in organic chemistry.

4. Which homologous series does C₅H₈ belong to?

Alkane

Alkene

Alkyne

C5H8 belongs to the alkyne homologous series because it has a triple bond between two carbon atoms. Alkynes are hydrocarbons that contain at least one triple bond between carbon atoms. In this case, C5H8 has 5 carbon atoms and 8 hydrogen atoms, and the presence of the triple bond indicates that it is an alkyne.

5. __________ are two or more compounds that have the same molecular formula but different molecular structure.

Isomers are two or more compounds that have the same molecular formula but different molecular structure. This means that they have the same number and types of atoms, but the arrangement of these atoms is different. Isomers can have different physical and chemical properties, as well as different biological activities. They are important in fields such as medicine and chemistry, as they allow scientists to study the effects of structural changes on the properties of compounds.
