Question

5) write the two Properteies of alkalines ?​

Answer 1

Alkanes are colourless. Alkanes are less dense than water (alkanes float on top of water). Alkanes are non-polar molecules so they are more soluble in non-polar solvents than they are in polar solvents. Alkanes are insoluble in water

Answer 2

Your answer ☆

• Physical Properties of Alkanes:
• The melting and boiling points of the shorter chain alkanes is low, but the melting and boilings of alkanes increase as the number of carbon atoms in the carbon chain increases.
• Alkanes are colourless.
• Chemical Properties of Alkanes:
• Alkanes will react with halogens such chlorine gas and bromine water in the presence of ultraviolet light.
• Alkanes combust (react rapidly with oxygen) releasing energy, which makes alkanes useful as fuels.
