9 isomers of a heptane in condensed structured formula and also the iupas name
Answer (2)
- Testosterone is the primary male sex hormone, responsible for developing and maintaining male characteristics.- Estrogen and progesterone are primarily female sex hormones.
Nine Isomers of Heptane with Condensed Structural Formulas and IUPAC NamesHeptane (C₇H₁₆) is an alkane with nine possible isomers, which are structural variations where the molecular formula remains the same but the connectivity of atoms differs. These isomers can be either straight-chain or branched structures. Below are the nine isomers of heptane, along with their IUPAC names and condensed structural formulas:1. n-Heptane (Straight-chain heptane)IUPAC Name: HeptaneFormula: CH₃(CH₂)₅CH₃2-MethylhexaneFormula: CH₃CH(CH₃)(CH₂)₄CH₃3-MethylhexaneFormula: CH₃CH₂CH(CH₃)(CH₂)₃CH₃2,2-DimethylpentaneFormula: CH₃C(CH₃)₂(CH₂)₃CH₃2,3-DimethylpentaneFormula: CH₃CH(CH₃)CH(CH₃)(CH₂)₂CH₃2,4-DimethylpentaneFormula: CH₃CH(CH₃)(CH₂)CH(CH₃)CH₃3,3-DimethylpentaneFormula: CH₃CH₂C(CH₃)₂(CH₂)₂CH₃3-EthylpentaneFormula: CH₃CH₂CH(CH₂CH₃)(CH₂)₂CH₃2,2,3-TrimethylbutaneFormula: CH₃C(CH₃)₂CH(CH₃)CH₃These isomers differ in the placement of methyl (-CH₃) and ethyl (-C₂H₅) groups, affecting their physical and chemical properties, such as boiling points and densities. Straight-chain alkanes like n-heptane tend to have higher boiling points, while branched isomers experience lower boiling points due to weaker intermolecular forces. These variations in structure make different isomers useful in fuel, solvents, and industrial applications. Understanding these nine isomers helps in organic chemistry, particularly in hydrocarbon classification and reactivity.
