boiling point usually high
1413 °C , inorganic
Combustion formula for Alkane
Alkane(g)+O₂(g)→∆ CO₂+H₂O(g) + energy
4 carbon
Butane example: C₄H₁₀
Propene (monomer)
CH₃ | H₂C=CH
condensed structural formula ethane
CH₃-CH₃
condensed structural formula of methane
CH₄
As the number of carbon atoms increases, there is also an increase in the number of electrons, which increases the attraction because of the dispersion forces.
Alkanes with higher masses have higher melting and boiling points
3 carbon
Propane example: C₃H₆
1st four alkanes: methane, ethane, propane, and butane
are gases at room temperature and are widely used as heating fuels
aniline
benzene with an amino group (-NH₂)
Phenol
benzene with hydroxyl (-OH)
Cycloalkanes have higher
boiling points than the straight-chain alkanes with the same number of carbon atoms
Example of organic compound
urea
Tertafluroethene monomer
F F | | F- C= C-F
1,1-dichloroethene monomer
Cl | H₂C =C-Cl

inorganic
particles: mostly ions: Na+ and Cl-
inorganic
Alkanes having five to eight carbon atoms: pentane, hexane, heptane, and octane) are
liquids at room temperature. They are highly volatile, which makes them useful in fuels such as gasoline
Alkanes have the lowest
melting and boiling points of all the inorganic compounds
Melting point: usually low -188 degrees Celsius organic or inorganic
organic
Solubility in water: not soluable unless a polar group is present
