Which structural formula represents a member of the series of hydrocarbons having the general formula CnH2n-2?

Final answer: The hydrocarbons with the general formula CnH2n-2 are alkynes, characterized by a carbon-carbon triple bond. An example is ethyne or acetylene (H-C≡C-H). They are less saturated than alkanes and alkenes and have distinctive properties. Explanation: The hydrocarbons with the general formula CnH2n-2 belong to a class of hydrocarbons known as alkynes. Alkynes are characterized by the presence of a carbon-carbon triple bond. An example of a molecule in this series is ethyne, commonly known as acetylene, with a structural formula of H-C≡C-H. In this formula, there are two carbon atoms (n=2), and there are 2(2)-2=2 hydrogen atoms, which is consistent with the general formula CnH2n-2. Unlike alkanes (which have a general formula of CnH2n+2) and alkenes (which have a general formula of CnH2n), alkynes are less saturated because they have fewer hydrogen atoms relative to carbon atoms. The triple bond in alkynes also leads to distinctive physical and chemical properties, including a linear molecular geometry around the carbon atoms participating in the triple bond.

Final answer: Hydrocarbons with the general formula CnH2n-2 belong to the series of alkynes, exemplified by acetylene. Alkenes and alkanes have different general formulas and single or double bonds, respectively, between carbon atoms. Structural isomers can exist due to different arrangements of atoms. Explanation: The hydrocarbons with the general formula CnH2n-2 belong to the series of alkynes. An example of this in a structural formula is ethyne, commonly known as acetylene, with the formula H-C≡C-H. In this molecule, each carbon atom is bonded to one hydrogen atom and to the other carbon atom by a triple bond. This triple bond is characteristic of alkynes and differentiates them from alkenes, which have one double bond, and alkanes, which just have single bonds. Alkanes have the general formula CnH2n+2 and alkenes have the formula CnH2n. Different structural arrangements of atoms in these series can lead to the formation of constitutional isomers. For example, n-butane and 2-methylpropane, both of which belong to the alkane series, are structural isomers. Learn more about Hydrocarbon Structure here: brainly.com/question/30219121 #SPJ11
