The Relative Stabilities of Cycloalkanes: Ring Strain

  The Relative Stabilities of Cycloalkanes: Ring Strain ** Cycloalkanes do not all have the same relative stability. Experiments have shown that cyclohexane is the most stable cycloalkane and that, in comparison, cyclopropane and cyclobutane are much less stable. This difference in relative stability is due to ring strain, which comprises …

Sigma Bond and Bond Rotation

– In this subject, we will discuss the Sigma Bond and Bond Rotation – Two groups bonded by only a single bond can undergo rotation about that bond for each other: – The temporary molecular shapes that result from such a rotation are called conformations of the molecule. – Each possible structure …

Nomenclature of Cycloalkanes: Monocyclic, Bicyclic

– In this subject, we will discuss the Nomenclature of Cycloalkanes: Monocyclic, Bicyclic What are Cycloalkanes? – Saturated cyclic hydrocarbons are called cycloalkanes, or alicyclic (aliphatic cyclic) compounds, and have the general formula (CH2)n or CnH2n.  – Cycloalkanes are named by adding “cyclo” before the parent name of the alkane. – …

Functional Groups in Organic Chemistry

– In this subject, we will discuss the Functional Groups in Organic Chemistry. Functional Groups – Carbon combines with other atoms (e.g., H, N, O, S, halogens) to form structural units called functional groups. – Functional groups are important for three reasons. – First, they are the units by which …
