Chemistry stack exchange.

The covalent bond is the electrostatic interaction between two atoms in the same molecule. Covalent bonds are much stronger than hydrogen bonds: the O−H O − H has a strength of 467 kJ/mol, while the hydrogen bond is usually between 4 to 40 kJ/mol. Just want to point out that there is a subtlety to the word "water": Feb 10, 2014 · 5. Hyperconjugation is the interaction between adjacent orbital (empty p p for cation, π π for alkene) with σ σ bond, while common conjugation is between adjacent orbital and π π bond. As one example, one reason why more alkyl substituted alkenes are more stable than less substituted ones is because more alkyl groups provide more ... When explained properly, resonance is a consequence of our unability to draw adequate depictions of what the bonding situation in the molecule truly looks like. For example, take a benzene ring. We can only draw single and double bonds. The structures should be identical whether the double bonds are in 1,3,5 or 2,4,6 positions.Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, ...

R L i + R ′ X ↽ − − ⇀ K R ′ L i + R X. As an equilibrium process, we know that the more stable lithium species is preferred. Interestingly when R′ R ′ = aryl (particularly bromides and iodides) this is best written as,

There are two reactivities of carbon dioxide that might form a problem in certain contexts. The first one is the (weak) acidity of carbonic acid, which could lead to reactions with bases. This is important especially in titrations when a specific concentration of base is desired which should remain stable over time.

This contracts the Bohr radius of the 1s electrons by ~22%. Source: Wikipedia. This also contracts the size of other orbitals, including the 6s. The absorption you see is a 5d → 6s transition.

This is because of something called penetration . The mathematical shapes of d-orbitals prevent them from allowing electrons to penetrate very closely to the nucleus, compared with electrons in s ...Stack Exchange is a network of question-and-answer (Q&A) websites on topics in diverse fields, each site covering a specific topic, where questions, answers, and users are subject to a reputation award process.

Dec 2, 2022 · The intersection between the wafer surface and the (122) plane is a line parallel to (1,1,1) x (1,2,2) = (0,-1,1). The angle between these two is 120 degrees. Because of the symmetry of the wafer, other solutions are 0 or -120 degrees. (You would get those by dialing in the (212) or the (221) plane.)

Carbon Dioxide (CO 2) readily dissolve in water and form Carbonic Acid (i.e H2CO3 (aq) ) This is the formation of bonds. Then Carbonic Acid (i.e H 2 CO 3 (aq) ) dissociate in water as follows. So water gets H + ions, so that cause water acidic. The following shows dissociation of Carbonic Acid (i.e H 2 CO 3 (aq) ) more clearly.Jan 20, 2014 · FeX2+ F e X 2 + ion containing metal surfaces, rust, drinking water, blood etc., but also copper and brass, give rise to a similar odor on contact with the skin.

In general, we can describe a quasi aromatic compound as a compound, which is ionic in nature with a counter ion, and the π π electrons in such compounds follow Huckel's rule ( 4n + 2 4 n + 2 ). In other words, quasi aromatic compounds are those in which the charges present on the molecule are a part of aromaticity of the compound.
