What are the axial and equatorial bond in cyclohexane?
The C-H bonds in cyclohexane are of two types: axial and equatorial (not equitorial! Think equator!) In structure A, the axial bonds have red hydrogens; the equatorial bonds have blue hydrogens. The equatorial bonds, or hydrogens, lie about the “equator” of the cyclohexane ring, or in the “plane” of the ring.
Which conformation is more stable axial or equatorial of methyl cyclohexane?
chair conformation
The most stable conformation of methylcyclohexane is the chair conformation in which the methyl group is equatorial. The alternative chair conformation, in which the methyl group is axial, is 7.3 kJ/mol higher in energy.
What is the difference between axial and equatorial?
The key difference between axial and equatorial position is that axial bonds are vertical while equatorial bonds are horizontal. The terms axial and equatorial are important in showing the actual 3D positioning of the chemical bonds in a chair conformation cyclohexane molecule.
When methyl group is in axial position in methyl cyclohexane The molecule has?
Therefore, here as per the given question, when the methyl group (which is bulkier than the hydrogen atom) occupies an axial position, it will suffer steric hindrance by the two axial hydrogens located on the same side of the ring.
Which orientation of the methyl group axial or equatorial is higher in energy?
This is absent in the conformation where methyl is equatorial. This gauche interaction is an example of van der Waals strain, which is what makes the axial conformer higher in energy.
What is equatorial and axial position?
Axial and equatorial are types of bonds found in the chair conformation of cyclohexane. The chair conformation is the most stable conformation of cyclohexane. Axial positions are perpendicular to the plane of the ring and equatorial positions are around the plane of the ring.
What is the structure of methylcyclohexane?
Methylcyclohexane is a cycloalkane that is cyclohexane substituted by a single methyl group. It has a role as an aprotic solvent, a plant metabolite and a human metabolite. It is a cycloalkane and a volatile organic compound. It derives from a hydride of a cyclohexane.
What is the chair structure of cyclohexane?
Cyclohexane and the Chair Structure: The chair structure of cyclohexane is considered to be the “perfect” conformation. The chair structure consists of a six-membered ring where every C-C bond exists in a staggered conformation.
What is methylcyclohexane used for?
Methylcyclohexane is a cycloalkane that is cyclohexane substituted by a single methyl group. It has a role as an aprotic solvent, a plant metabolite and a human metabolite. It is a cycloalkane and a volatile organic compound.
