Alkanes are referred to as saturated hydrocarbons that are, hydrocarbons having all carbon atoms bonded to other carbon atoms or hydrogen atoms with sigma bonds only.
Melting point of the symmetrical alkanes
- The molecules with symmetrical structures fit better in the crystal lattice and hence the melting point of symmetrical molecules is more.
- Molecular symmetry has a great effect on the melting properties and solubility of organic compounds.
- As a general rule, symmetrical molecules in crystalline form have higher melting temperatures and exhibit lower solubilities compared with molecules of similar structure but with lower symmetry.
