Polarity is about PARTIAL charges. There is no real charge involved. For example water (H2O) is a polar molecule, because O has a stronger electronegativity than H (that means O attracts electrons stronger than H). Because of this attraction the electrons are often next to the O and so we can say that O has a negative partial charge and both H's has a positive <span>partial </span>charge.
Non polar means no partial charged.
I hope I could help a bit (and sorry for the bad english)
Answer:
Yes
Explanation:
The compounds have both hydrogen and carbon only which are atoms that make up the hydrocarbons and they are also gases at room temperature
