The reason d-orbitals make a difference is that electrons in d-orbitals do not screen nuclear charge as effectively as those in s and p orbitals. 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 ...It’s important to have a variety of options when you’re looking for a new internet service plan so you can find the best one for your needs.

This is so because Sp2 hybridised orbitals are lower in energy than Sp3 hybrid orbitals (The more the S character the lesser is the energy of the orbital). When there is a lone electron present, it is more efficient to keep the bond pair electrons in lesser ...Thanks for contributing an answer to Chemistry Stack Exchange!

It does not occur in your molecules. According to me, while comparing acidic strength, we should remove H X + from both the compounds, hence we get C F X 3 − O X − and C C l X ...Just a guess- Lithium cation is smaller than the sodium cation, so the size of LiOH must be smaller than NaOH. Hence, the electrons will be pulled strongly, and it will be harder for them to leave. Hence, it would be a weaker base. Also, Lithium compounds are largely covalent, which could again be a possible reason.

Follow our policies when asking homework-like questions (questions about problem sets, exam items, etc.).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.)4. There are two ways to think of charge separation and both make resonance structures less stable: Moving electrons from a bond to a single atom to generate a cation/anion pair. For example: RX2C=CH−CH=CRX2 RX2C=CH−C+H−C−RX2 R X 2 C = C H − C H = C R X 2 R X 2 C = C H − C + H − C − R X 2.I was looking for the pKa p K a of imidazole and found this pKa p K a table [1]: Compound Imidazolium 2-Aminoimidazolium 1-Methyl-2-aminoimidazolium 4,5-Dimethyl-2-aminoimidazolium pKa 7.38 8.46 8.65 9.21 Compound p K a Imidazolium 7.38 2-Aminoimidazolium 8.46 1-Methyl-2-aminoimidazolium 8.65 4,5-Dimethyl-2-aminoimidazolium 9.21.Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry.

May 16, 2012 · The AgX+ A g X + ion and the ClX− C l X − ion are close to the same size (with the silver ion being smaller), so they can approach each other quite closely. In silver nitrate, the NOX3X− N O X 3 X − ion is larger and does not allow as close an approach as the chloride ion, so the bond is weaker, easier to break up, and the salt is more ... From chemistry stack exchange, an answer contributed by user R.M.: SMARTS is deliberately designed to be a superset of SMILES. That is, any valid SMILES depiction should also be a valid SMARTS query, one that will retrieve the very structure that the SMILES string depicts. Except, that last clause isn't true. Try matching tritium against itself.Effect of Temperature on pH of Water. The Kw K w is a function of temperature. It is 10−14 10 − 14 at 25 ∘C 25 ∘ C. When the temperature is 50 ∘C 50 ∘ C, the Kw K w can be calculated to be somewhere around 10−12 10 − 12 using Vant Hoff's equation, but this is so weird.Thanks for contributing an answer to Chemistry Stack Exchange!

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. 2 Answers. 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.
