Alkanes, usually a hydrocarbon forms like methane, ethane etc.

✨Physical properties:
All alkanes are colourless and odourless

Name//Formula//Boiling point [°C]//Melting point [°C]//Density [g·cm−3] (at 20 °C)
Methane//CH₄//−162//−182//gas
Ethane//C₂H₆//−89//−183//gas
Propane//C₃H₈//−42//−188//gas
Butane//C₄H₁₀//0//−138//gas
Pentane//C₅H₁₂//36//−130//0.626 (liquid)
Hexane//C₆H₁₄//69//−95//0.659 (liquid)
Heptane//C₇H₁₆//98//−91//0.684 (liquid)
Octane//C₈H₁₈/126//−57//0.703 (liquid)
Nonane//C₉H₂₀//151//−54//0.718 (liquid)
Decane//C₁₀H₂₂//174//−30//0.730 (liquid)

The list will go on. You will understand better by this separated information than the full-length paragraphs. But I prefer you to visit https://en.wikipedia.org/wiki/Alkane once to have each and every information you want . Hope it helped. ^_^
