Structure and Name of the 5th Member Alkene Group

Introduction
Alkenes are unsaturated hydrocarbons that contain a carbon-carbon double bond. They are characterized by the general formula CnH2n, where "n" represents the number of carbon atoms present in the molecule. The alkene group refers to a specific homologous series of organic compounds that possess a double bond between two adjacent carbon atoms.

Definition of Alkene Group
The alkene group is a class of organic compounds that contain at least one carbon-carbon double bond. This double bond consists of a sigma (σ) bond formed by the overlapping of sp2 hybridized orbitals and a pi (π) bond formed by the sideways overlap of p orbitals. The presence of the double bond imparts unique chemical and physical properties to alkenes, making them important building blocks in organic synthesis.

5th Member of the Alkene Group
The 5th member of the alkene group corresponds to the alkene with five carbon atoms in its structure. According to the general formula CnH2n, this alkene will have the molecular formula C5H10.

Structure and Name
The structure of the 5th member alkene group, C5H10, is represented by the following structural formula:

CH2=CH-CH2-CH2-CH3

The name of the 5th member alkene is pent-1-ene. Let's break down the name to understand its components:

1. Prefix: "Pent-" indicates that there are five carbon atoms in the molecule.
2. Suffix: "-ene" signifies that the compound belongs to the alkene group, indicating the presence of a carbon-carbon double bond.
3. Position: "1-" indicates that the double bond is located between the first and second carbon atoms in the chain.

Conclusion
The 5th member of the alkene group is known as pent-1-ene. It is an organic compound with five carbon atoms and a carbon-carbon double bond between the first and second carbon atoms. Understanding the structure and nomenclature of alkene compounds is important in organic chemistry as it allows for effective communication and identification of specific compounds within the alkene group.

C6H12 is the fifth member of alkene group. Its name is hexene.
