How is a hydrogen bond different from a covalent bond? How do hydrogen atoms make a covalent bond? What state of matter has the strongest intermolecular forces? What are the properties of the molecules containing the intermolecular forces ion-dipole, dipole-dipole, dispersion, and hydrogen b...
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...
Which of the following gas has minimum molecular mass? 1) oxygen 2) nitrogen 3) hydrogen 4) methane 1. What is the electron configuration for chlorine? One common ion of chlorine is Cl ^1- . How many valence electrons does...
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...
Is oh a polar covalent bond? A molecule which has one or more polar covalent bonds may have a dipole moment as a result of the accumulated bond dipoles. In the case of water, we know that the O-H covalent bond is polar, due to the different electronegativities of hydrogen and oxygen...
Which is the strongest halogen acid? 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?
What is the strongest interparticle force in CH3OH? A) disperion B) hydrogen bonding C) dipole-dipole Which of the compounds have only dispersion forces? a. CH3OH b. NH2CH3 c. C8H18 d. C3H8 Which of the following compounds will not form a hydrogen bond? a. CH2F2 ...
is, the lack of van der Waals forces at the PTFE surface - is usually attributed to the very strong C-F single bond, and the extremely low polarizeability of fluorine. Fluorine is so electronegative that it holds its electrons very close to the nucleus, which lowers the probability that ...
HA and HB are both weak acids although HB is the stronger of the two. Will it take a larger volume of a 0.10 M NaOH solution to neutralize 50.0 mL of 0.10 M HB than would be needed to neutralize 50.0 Explain why the strongest acids are assigned the lowest pH values. ...
Why is phenol acidic? Phenol is acidic in naturebecause it can lose hydrogen ions from its OH bond, as on losing this hydrogen phenoxide ion is formed which is stable. Though it is a weak acid it is in equilibrium with the phenolate anion C6H5O− which is also called phenoxide. ...
