IUPAC Nomenclature

In the realm of chemistry, the International Union of Pure and Applied Chemistry (IUPAC) has established a systematic nomenclature system to ensure uniformity in naming chemical compounds. This system provides clear and concise guidelines for assigning names to organic molecules, including cycloalkanes like 1,3-dimethylcyclohexane.

When naming cycloalkanes, IUPAC prioritizes the following steps:

• Identify the parent chain: The parent chain is the largest cyclic structure present in the molecule.
• Number the parent chain: Numbering begins at a carbon atom bearing a substituent and proceeds around the ring in a way that gives the lowest possible numbers to the substituents.
• Identify and name the substituents: Substituents are atoms or groups of atoms attached to the parent chain. They are named according to their structure and position on the parent chain.
• Combine the parent chain name and substituent names: The name of the cycloalkane is formed by combining the name of the parent chain with the names of the substituents, preceded by their respective numbers.

Applying these rules to 1,3-dimethylcyclohexane, we can break down its name as follows:

Parent Chain

The parent chain is a six-membered ring, indicating the “cyclohexane” portion of the name.

Substituents

There are two methyl groups (CH ₃) attached to the parent chain. One is located at carbon 1, and the other is at carbon 3.

IUPAC Name

Combining the parent chain name and substituent names, we arrive at the IUPAC name for 1,3-dimethylcyclohexane: 1,3-dimethylcyclohexane.

Molecular Geometry

The molecular geometry of 1,3-dimethylcyclohexane can be predicted using VSEPR theory, which states that the electron pairs around an atom will adopt an arrangement that minimizes repulsions between them. In this case, the carbon atoms in the ring are sp ³hybridized, meaning that they have four electron pairs arranged in a tetrahedral shape.

The two methyl groups are also sp ³hybridized, with three electron pairs arranged in a tetrahedral shape.

Bond Angles

The bond angles in 1,3-dimethylcyclohexane are all approximately 109.5 degrees, which is the ideal angle for tetrahedral geometry. The carbon-carbon bonds in the ring are all of equal length, and the carbon-hydrogen bonds are also all of equal length.

Conformational Analysis

Conformational analysis is the study of the different shapes that a molecule can adopt by rotating around single bonds. In the case of 1,3-dimethylcyclohexane, there are two possible conformations: the chair conformation and the boat conformation.

The chair conformation is the more stable of the two conformations because it has all of the substituents in equatorial positions. This means that the substituents are pointing away from each other, which minimizes steric hindrance.

The boat conformation is less stable than the chair conformation because it has one of the substituents in an axial position. This means that the substituent is pointing towards the other substituents, which causes steric hindrance.

Chair Conformation

• All substituents are in equatorial positions.
• More stable than the boat conformation.
• Less steric hindrance.

Boat Conformation

• One substituent is in an axial position.
• Less stable than the chair conformation.
• More steric hindrance.

Chemical Properties: Draw The Structure Of 1 3-Dimethylcyclohexane

1,3-Dimethylcyclohexane is a hydrocarbon compound with the molecular formula C8H16. It is a saturated cyclic hydrocarbon, meaning that all of its carbon atoms are bonded to hydrogen atoms and there are no double or triple bonds between carbon atoms. This structure makes 1,3-dimethylcyclohexane a relatively unreactive compound, but it can still undergo some chemical reactions.

One of the most common reactions of 1,3-dimethylcyclohexane is substitution, in which one of the hydrogen atoms on the molecule is replaced by another atom or group of atoms. For example, 1,3-dimethylcyclohexane can react with chlorine gas to form 1,3-dimethylcyclohexyl chloride.

This reaction is a free radical substitution reaction, which proceeds via a radical intermediate.

1,3-Dimethylcyclohexane can also undergo addition reactions, in which a new atom or group of atoms is added to the molecule. For example, 1,3-dimethylcyclohexane can react with hydrogen gas in the presence of a catalyst to form methylcyclohexane. This reaction is a hydrogenation reaction, which proceeds via a carbocation intermediate.

The structure of 1,3-dimethylcyclohexane influences its chemical properties in several ways. The cyclic structure of the molecule makes it more stable than a linear hydrocarbon with the same number of carbon atoms. This stability is due to the fact that the cyclic structure reduces the number of degrees of freedom of the molecule, which in turn reduces the entropy of the molecule.

The presence of the two methyl groups on the molecule also makes it more reactive than a cyclohexane without any substituents. This is due to the fact that the methyl groups donate electrons to the ring, which makes the ring more nucleophilic.

Reactivity towards Electrophilic Reagents, Draw The Structure Of 1 3-Dimethylcyclohexane

1,3-Dimethylcyclohexane is a relatively unreactive compound, but it can react with electrophilic reagents. Electrophilic reagents are compounds that are attracted to electrons, and they can react with 1,3-dimethylcyclohexane to form new compounds. One common type of electrophilic reagent is a halogen, such as chlorine or bromine.

When 1,3-dimethylcyclohexane reacts with a halogen, the halogen atom adds to the double bond, forming a new compound. For example, when 1,3-dimethylcyclohexane reacts with chlorine, it forms 1,3-dimethylcyclohexyl chloride.

Reactivity towards Nucleophilic Reagents

1,3-Dimethylcyclohexane can also react with nucleophilic reagents. Nucleophilic reagents are compounds that are attracted to protons, and they can react with 1,3-dimethylcyclohexane to form new compounds. One common type of nucleophilic reagent is a hydroxide ion. When 1,3-dimethylcyclohexane reacts with a hydroxide ion, the hydroxide ion attacks the carbon atom that is bonded to the methyl group, forming a new compound.

For example, when 1,3-dimethylcyclohexane reacts with a hydroxide ion, it forms 1,3-dimethylcyclohexyl alcohol.
