Polarity of Molecules - Page 4
Questions
- If you put a hydrophobic substance into a hydrophilic substance, what would happen?
- How can polar molecules pass through a membrane?
- What is the geometry of the #Cl-S-S-Cl# molecule?
- Why is water polar based on oxygen's pull on electrons as compared to Hydrogen's?
- Does #"C"_2# exist, and if so, describe its electron distribution?
- Is #"P"_2"Cl"_4# a polar or non-polar molecule?
- How do you determine if a molecule non polar?
- Why are the molecules of hydrocarbons nonpolar?
- Despite the large difference in electronegativity between #"Si"# and #"F"#, #"SiF"_4# has a boiling point lower than that of #"NH"_3# (#-86^@ "C"#, vs. #-33^@ "C"#). Why is that? Could it be due to the symmetry? Hydrogen-bonding?
- Can a molecule with nonpolar bonds be polar?
- Why most of the alkanes are Hydrophobic in nature?
- Water is characterized as a polar molecule. What does this mean?
- Why does the bonding of oxygen and hydrogen result in a polar molecule and hydrogen bonds?
- Which of these liquids is miscible with water? Ethanol, methanol, hexane... Why? I thought since ethanol has a nonpolar tail, it isn't soluble in water.
- How can polarity of molecules be predicted from their geometry?
- How does polarity affect chromatography?
- Why is methane nonpolar? Explain in terms of polarity within a bond, and overall polarity based on symmetry.
- Which would you expect to have the higher melting point(or boiling point): C8H18 or C4H10? Explain
- When do molecules become polar?
- What is the definition of a molecule?
