How hexane molecules attract to form a liquid
Web14 mrt. 2024 · The strongest intermolecular force in water is a special dipole bond called the hydrogen bond. Many molecules are polar and can form bipole-bipole bonds without forming hydrogen bonds or even having hydrogen in their molecule. Water is polar, and the dipole bond it forms is a hydrogen bond based on the two hydrogen atoms in the … Web5 minutes, use a clean, dry Pasteur pipette to transfer the liquid into another clean test tube. Label this test tube with an E for extract so that you do not confuse it with the test tubes you will be working with later in this experiment. Add about 0.5 mL hexane to rinse the hydrated sodium sulfate and transfer this liquid to the same test ...

Web29 feb. 2024 · Water is not very attracted to the oil and so does not dissolve it. Why does hexane not dissolve in water? Hexane cannot form hydrogen bonds with water. Water molecules experience much more attraction to one another than they do to hexane. Water molecules and hexane molecules cannot mix readily, and thus hexane is insoluble in … Web14 aug. 2024 · Liquids consisting of long, flexible molecules tend to have higher viscosities than those composed of more spherical or shorter-chain molecules. The longer the molecules, the easier it is for them to become “tangled” with one another, making it …
WebAs the Na loses its valence electron, the rest of the electrons are attracted to the nucleus with a force that is much stronger because there are more protons than electrons. And as Cl gains an electron, the forces between the electrons increases, causing them to expand and making the ion bigger. • 2 comments ( 32 votes) Luke Bayler 11 years ago Web2 apr. 2015 · The stream of water bends due to the polarity of water molecules. Video from: Noel Pauller The partial negative part of the ethanol molecule, i.e. the oxygen from the "-OH" group, will be attracted to the positively charged particles in the rod, causing the stream to be deflected.
Web8 apr. 2024 · When molecules of a substance stick together very firmly, it exists as a solid; when they stick somewhat firmly, the substance exists as a liquid; and when they barely … WebThe same phenomenon holds molecules together at the surface of a bulk sample of water, almost as if they formed a skin. When filling a glass with water, the glass can be overfilled so that the level of the liquid actually extends above the rim. Similarly, a sewing needle or a paper clip can be placed on the surface of a glass of water where it “floats,” even though …
