Which bond in each of the following pairs of bonds is the strongest and why? a. C-N or C-O b. C-H or O-H c. C≡O or C=O Bond Energies: One of the properties of a covalent bond is its bond energy (or bond enthalpy). This...
Bonds: Bonds are connections between atoms that are formed when atoms share or donate electrons. The electrons involved in bonding are in the outer shell and are known as valence electrons. Answer and Explanation:1 Hydrogen bonds are the strongest of intermolecular forces for covalent compounds ...
What must be always true if a covalent bond is polar? A molecule is polar if the shared electrons are equally shared. A molecule is nonpolar if the shared electrons are are equally shared. Which molecule is polar and contains polar bonds? A polar molecule is a molecule in which one end ...
when we pour liquid oxygen through a magnet, the molecules line up with the magnetic field, and the attraction allows them to stay suspended between the poles of the magnet where the magnetic field is strongest. Other diatomic molecules (like N2) flow past the magnet. ...
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...
Explain why, when a thermometer is placed in hot water, the column of mercury first descends slightly and then rises. (a) Briefly cite the main differences between ionic, covalent, and metallic bonding. (b) State the Pauli ex...
which of the following crystallizes as a molecular solid? please explain why KI AI2(SO4)3 CH3OH Molecular solid: Molecular solid is a solid made out of particles held together by the van der Waals powers. Since these dipole powers are more fragile than covalent or i...
Valence Bond Theory: The valence bond theory is a chemical bonding theory that describes how the overlap of half-filled atomic orbitals causes bonding between two atoms. The unpaired electrons of the two atoms are shared to produce a filled orbital and a hybrid orb...
Why is hydrogen bonding only possible with hydrogen? Why are hydrogen bonds the strongest of the intermolecular forces? Explain how the bonds in methane, ammonia, and water are formed, why there are differences in bond angles between the molecules, and why the molecules show different polar...
Is an intermolecular force the same as a chemical bond (either covalent or ionic)? Identify the predominant intermolecular forces in CH4. Does high vapor pressure indicate strong intermolecular forces or weak intermolecular forces in a liquid? Explain. Which of the substances have the strongest inter...
