Which compound has the strongest hydrogen bonding between its molecules? Explain dipole-dipole interaction, hydrogen bonds, and van der Waals forces. Give examples also. How are ionic and covalent bonds different from hydrogen bonds? How are hydrogen bonds, ionic bonds and covalent bonds differe...
The strongest H-bonds are obtained as a result of a concerted push–pull effect of four peripheral water molecules, which polarize the electron density in a way that supports charge transfer and partial covalent character of the targeted H-bond. For water molecules with tetra- and penta...
What is the importance of rinsing the pH electrode after each sample? Why does a lake's location determine the pH level? Why might pH fall in a culture medium when bacteria are actively growing? Why is H3O+ the strongest acid in biological systems?
Which bonds are the strongest and weakest? The ranking from strongest to weakest bonds is: Covalent bond > ionic bond > hydrogen bond > Van der Waals forces. Complete answer: The order from strongest to weakest bonds is: Covalent bond > ionic bond > hydrogen bond >Van der Waals forces. ...
Explain why hydrogen fluoride(HF)has a higher boiling temperature than hydrogen chloride(HCl) (19.4oC vs. - 85oC), even thoughHFhas a lower molecular weight Van Der Waals Forces: Van Der Waals forces are relatively weak electric...
as an electron donor (“base”) and the halogen as an electron acceptor (“acid”). studied,I Clis the strongest “acid,” followed by I2 and then Br2. How many OH bonds does the oleum molecule contain? The compounds contain4 bonds. Four oxygen atoms are linked to sulphur by double ...
Which of the following can form intermolecular hydrogen bonds? a) H2CO b) PH3 c) (CH3)2NH d) CH3COCH3 What is the molecular polarity using dipole vectors and intermolecular forces of SiH4, CH3OH, HCN, and CH3F? What is the most important (strongest) intermolecular for...
the substance, determine whether there are likely to be dipole-dipole interactions, hydrogen bonds, or London forces, and make some arbitrary but straightforward assessment of the overall strength of these interactions based on the magnitudeand numberof the forces identified as important. It's ...
Magnetars are a special kind of neutron star, and neutron stars are a special kind of dead star. They're easy enough to make — if you're a massive star. All stars fuse hydrogen into helium deep in their cores. The energy released supports the stars against the crushing weight of ...
If water were a linear molecule: (a) would it still be polar? (b) would the water molecules still be able to form hydrogen bonds with one another? When a water molecule forms a hydrogen bond with another water molecule, which ato...
