Why hexane is a nonpolar solvent?
Answer:
hexane is a covalently bonded molecule. covalent bonded molecules like hydrocarbons usually arent able to be dissolved into water. therefore, it doesnt separate into negatively and positively charged parts when dissolved. only ionic bonds do this. hope this helps
Hexane is a symetrical structure and does not have a more negative and more positive end. Things like H2O have a definately negative and positive end making them polar.
Because it is composed of only C and H. It is very symmetrical and has no polar functional groups to impart any polarity
It's nonpolar because it has no atoms that are very electronegative (such as O2). Also, it is symmetrical due to the 6 carbons and the various hydrogens that fulfill the octet rule.
think about it this way
if there of two people pulling on a rope with equal force one person won't pull more than the other.
the two polar sides of hexane (their polarity determined by the difference of electronegativities) in a symmetric pattern with both sides pulling on eachother will cancel out the polarity.
Think of non-polar solvents as boring. Basically the molecule is symetrical. Its a boring molecule so to speak. In hexane each carbon is bonded to an adjacent carbon and has all of its non-carbon sites filled with "H" hydrogen atoms,so nothing "sticks out". An alcohol is not boring(polar) because one end is different (interesting) than the other end.
