How is a hydrogen bond different from a covalent bond? Why is fluorine more electronegative than chlorine? Why are covalent bonds between hydrogen and nitrogen or oxygen polar? What is water's bond angle? Why,
Discuss the relative strength of dipole-dipole interactions, hydrogen bonding, and London dispersion forces. Why do polar covalent compounds have higher melting and boiling points than non-polar covalent bonds with the same molecular mass? Are London forces typically stronger ...
The clear answer is PTFE. That's kind of indisputable. But it's pertinent to ask why. Fluorine is heavier than hydrogen and thus PTFE strands might be assumed to be higher molecular weight than LDPE. But that's neither here nor there. The real reason is mass and electron density. The ...
Therefore, you would expect the permanent dipole-dipole interactions to be weak, unlike the stronger hydrogen bonding in NH3. Induced dipole-dipole van der Waals interactions, that are present between all molecules (whether polar or non-polar), would play a significant role in the intermolecular a...
Which is stronger: an ionic bond or a covalent bond? Explain. Why are hydrogen bonds the strongest intermolecular forces? Why does the Xe-F bond of XeF_4 have smaller dipole than XeF_2? Provide a brief explanation as to why atoms may have different values of electronegativity. 1. Why doe...
Why is the stratosphere warmer than the upper troposphere? Why are the thermosphere and exosphere the warmest? Why isn't Earth's atmosphere mostly hydrogen? Why are aerosols and fumes not subject to gas laws? Why does ground-level ozone form when its warm?
Hydrogen bonding is much stronger than the van der waal forces. Answer and Explanation: Iodine solid is made from I2 molecule. The two iodine atoms in a molecule are bonded through covalent bond, and covalent bonds are strong...Become a membe...
Are hydrogen bonds polar or nonpolar? Why are covalent bonds between hydrogen and nitrogen or oxygen polar? Why, despite HF being stronger than H2O, does it have a lower boiling point? Explain. Is H2CO polar or nonpolar? Why is NH3 polar? What is the Lewis dot structure for CH4? Why ...
There are three types of intermolcular attractions or forces: london dispersion forces, dipole-dipole, and hydrogen bonds. Each is a representation of polarity with hydrogen bonds being the most polar followed by dipole-dipole. And london dispersion forces are the least polar inter...
Lewis Structure: The valence electrons in an atom are depicted as dots in Lewis structures, visual representations of molecules. Because it aids in forecasting the quantity and nature of bonds that can be formed around an atom, the Lewis dot struc...
