Properties of alkanes

Answer 1

link

• Non-Polar- Alkanes are hydrocarbons. Carbon and hydrogen have very similar electronegativities making alkanes non-polar

-Insoluble in water- As water molecules form hydrogen bonds with each other. Alkanes cant form hydrogen bonds because they have no permanent dipole Therefore can not dissolve in water.

• Generally unreactive
• London forces
• More surface point of contacts = increase london forces
• Branched alkenes have lower boiling points as it prevents alkenes getting closer together so london forces are reduced
