Shapes of Alkanes. “Straight-chain” alkanes have a . zig-zag. orientation when they are in their most straight orientation. 4-5. Rings larger that cyclohexane have more strain.. Bond angle distortion. Partial eclipsing of hydrogens. Transannular. steric repulsions. Medium sized rings adopt several conformations that are very close in energies, such as . Hydrocarbons are composed, as their name suggests mainly of carbon and hydrogen atoms, though some types have oxygen, nitrogen or . sulphur. atoms. . Hydrocarbons are divided into two groups, . Aliphatics. Straight chain alkanes will have symmetrical . electronegativities. so they will behave as non-polar molecules. Since ‘like dissolves like’ the alkanes will all be soluble in . eachother. However… since water is polar; alkanes will NOT dissolve in water… think of pouring oil on water. . Alkanes. Dr. . Shatha. I . Alaqeel. 1. 108 . Chem. Learning Objectives. Chapter one discusses the following topics and the student by the end of this chapter will:. . Know the classification of hydrocarbon. t. Alkanes have only single, covalent, non-polar bonds. Alkanes are relatively inert to most chemical reagents. Alkanes are also called . paraffins. (“little affinity”). 1. Combustion Reaction. Organic Compounds: Alkanes and Their Stereochemistry.
