Explain in detail why of all the intermolecular forces, the hydrogen bond is the strongest. Which has the stronger intermolecular forces: N2 or H2O? Explain. What are the intermolecular forces? What do intermolecular forces have to do with the states of matter?
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...
Explain why hydrogen fluoride (HF) has a higher boiling temperature than hydrogen chloride (HCl) (19.4{eq}^o{/eq}C vs. - 85{eq}^o{/eq}C), even though HF has a lower molecular weight Van Der Waals Forces: Van Der Waa...
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. Why ortho nitro phenol is ...
Considering that a typical coordination sphere of Ag2+ takes the form of a distorted octahedron, in order to provide the shortest bond lengths possible (and thus the strongest electronic and magnetic interactions), one must focus on the 2(+ 4) case (compressed Oh) rather than the 4(+ 2)...
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 ...
How is a hydrogen bond different from a covalent bond? How do a pure covalent bond, a polar covalent bond, and an ionic bond differ? Because carbon dioxide has 2 atoms bonded to it plus 2 electron pairs I see why the electron geometry is tetrahedral but my chart says that because of ...
Why is water unable to break a covalent bond? Why is oxygen considered a perfectly or purely covalent compound? Why is a hydrogen bond the strongest type of bond between molecules? Why doesn't H_2 form covalent bonds? Why do atoms bond? Why are ...
Why is HCl a stronger acid than CH3COOH? Why is acetic acid considered a weak acid? Explain. Why is acid added to the water not the water to the acid? Explain why the strongest acids are assigned the lowest pH values. Explain why p-methoxybenzoic acid is a weaker acid than benzoic acid...
What are the Lewis structures for a hydrogen and a hydroxide ion? Identify the Lewis acid and Lewis base. AlCl_3 (s) + Cl^- (aq) to AlCl_4^- (aq) Why are alcohols susceptible to attack by a base? Explain why the bond in an alcohol is larger than that of water and is ...
