Also, the shape of the DOF as a function of the reaction coordinate reveals the existence of avoided MO crossings and their location on the RC. Even for spontaneous reactions with monotonic variation in the potential energy, extrema of the MO energy and sudden electron rearrangements can be put...
Short Summary The four simple reactions we discussed in this lesson are the basis for most reactions that you'll see in organic chemistry. The four main types of reactions in organic chemistry include substitution 1 (Sn1), substitution 2 (Sn2), elimination 1 (E1), and elimination 2 (E2)....
Here coupling reactions took place. The coupling of Gilman reagents with second alkyl halide (X can be chloride, bromide or iodide) is useful in organic synthesis because it forms a carbon bond. During this reaction one of the alkyl groups from the Gilman reagents replaces the halogen to form...
Nucleophile is a Word Used to Refer to Substances that tend to Donate Electron Pairs to Electrophiles and form Chemical Bonds with Them in Chemical Reactions. Learn about Nucleophiles Here.
Is hydration SN1 or Sn2? Acid catalyzed hydration of alkenes is not a substitution reaction; instead, it is an addition reaction. This means that is it not Sn1 or Sn2. Hydration is adding a water molecule; it is not substituting the water molecule for another molecule on the compound. Wh...
Stereochemistry of the Diels-Alder Reaction Diels-Alder / Retro Diels Alder Reactions of Tetrazines (Loss of N2) This could be a bad analogy, but theretro-Diels Alder reminds me a little bit of the famous “adrenaline shot” scene inPulp Fiction. ...
might contribute to the pi system as well, giving 8 pi electrons total. However, that lone pair is in theplaneof the molecule (along with the other C-H bonds) and thus can’t overlap with the p-orbitals. Therefore, for the purposes of determining aromaticity, we can ignore the lone ...
