WebThe alkanes are saturated hydrocarbons: hydrocarbons , because they are compounds containing hydrogen and carbon only saturated , because their carbon atoms are joined by C-C single bonds WebAlcohols have higher boiling points than do alkanes, alkenes, and alkynes of similar molecular weight, because alcohol molecules associate with one another in the liquid state by hydrogen bonding. Because of increased London dispersion forces between larger molecules, the boiling points of all types of compounds, including alcohols, increase ...
WebThe boiling point of alkanes increases with increasing molecular weight. The straight-chain alkanes are observed to have a higher boiling point in comparison to their structural isomers. 4. Melting Point of Alkanes. The melting point of alkanes follows the same trend as their boiling point, that is, it increases with an increase in molecular ...
