Chem4Kids.com! This tutorial introduces chemical compounds. Other sections include matter, elements, the periodic table, reactions, and biochemistry. Sulfonic acids and carboxylic acids are rather electron-withdrawing, but if you drill down into the details of these ipso-substitution reactions, many are actually conducted on the conjugate base (i.e. sulfonate or carboxylate), which also provides a pathway for loss of a neutral group in the second step, i.e. $\ce{SO3}$ or $\ce{CO2}$.

  1. Jun 14, 2020 - We have seen earlier how alkyl halides undergo E1 and E2 elimination reactions to form alkenes: In those reactions, the leaving group was the halide which was kicked out by removing the β-hydrogen and making a new π bond.
  2. In many cases one major product will be formed, the most stable alkene. In terms of regiochemistry, Zaitsev’s rule states that when more than one product can be formed, the more substituted alkene is the major product. Unlike E2 reactions, E1 is not stereospecific. Thus, a hydrogen is not required to be anti-periplanar to the leaving group.
  3. The reaction, therefore, proceeds to products. The reaction of a phenol, however, favors the reactants since the pKa of phenol (10) is larger than that of the carbonic acid (6.4). Acid-base reactions favor the side with the weaker acid (that is, they favor the side with the larger pKa).

  5. q This strategy works because the azide anion is a strong nucleophile, but the neutral organic azide is a very weak nucleophile (recall that hydroxide anion is a strong nucleophile, but its neutral conjugate acid, water, is a very weak nucleophile). Therefore, the organic azide, once formed, is unable to react with the alkyl halide.
  6. Each carbon next to that is β carbon and a double bond can be formed between any two C atoms – one is always α, the other β. In the E1 reaction, we can obtain three different products because we have three β carbons. But when we draw all these products, we can see that disubstituted alkenes are the same when rotating the structure.
  7. The hydrolysis of nitriles, which are organic molecules containing a cyano group, leads to carboxylic acid formation. These hydrolysis reactions can take place in either acidic or basic solutions. The mechanism for these reactions involves the formation of an amide followed by hydrolysis of the amide to the acid. The mechanism follows these ...

  20. Nucleophilic acyl substitution describe a class of substitution reactions involving nucleophiles and acyl compounds.
