Coulson and Moffitt’s modification, also known as the bent bond or banana bond model, is a theoretical concept proposed in organic chemistry to explain the stability of certain strained molecules, particularly cycloalkanes. This model builds upon the traditional understanding of bond angles and hybridization to more accurately describe the bonding …

Sachse Mohr’s theory (Theory of strainless rings)
1918 Sachse and Mohr’s Argument Sachse and Mohr’s Proposal Implications of Strainless Rings Cyclohexane as an Example Boat Conformation Chair Conformation Stability Enhancement The concept of strainless rings holds significant implications for the design and synthesis of cyclic organic compounds. It proposes that specific ring sizes and structural features have …
Stability of cycloalkanes
The stability of cycloalkanes, which are cyclic hydrocarbons with only single carbon-carbon bonds, is influenced by factors such as ring strain and molecular geometry. Here’s a detailed note on the stability of cycloalkanes: Â 1. Ring Strain Angle Strain: Cycloalkanes with smaller rings (such as cyclopropane and cyclobutane) experience angle strain …
Chemical properties of cycloalkane
Cycloalkanes are a class of hydrocarbons featuring a circular arrangement of carbon atoms. The cyclic structure introduces a distinct degree of strain to these compounds, thereby impacting their chemical characteristics. Despite displaying lower reactivity when compared to their linear counterparts, cycloalkanes remain capable of participating in a variety of chemical …
Method of preparation of cycloalkanes
1. From Di-halogen Compounds: Suitable 1,3 or 1,4 di-halogen alkanes react with sodium or zinc to form cycloalkanes. 2. From Aromatic Compounds: Benzene can be converted into cyclohexane through catalytic hydrogenation at high temperature and pressure. 3. From Calcium or Barium salts of Dicarboxylic acids: Heating the calcium or barium …
Cycloalkanes: Definition, Nomenclature, Examples
Cycloalkanes constitute a category of organic compounds distinguished by the presence of one or more carbon-carbon single bonds organized in a closed ring or cyclic structure. This group falls within the broader category of alkanes, which are saturated hydrocarbons composed of carbon and hydrogen atoms linked together exclusively by single …
