WebSubstitution does not usually involve a large entropy change, so if S N 2 is desired, the reaction should be done at the lowest temperature that allows substitution to occur at a reasonable rate. Also, a strong hindered base … WebDehydration reactions involve the loss of water. These reactions commonly occur during the attachment of two units through the H molecule of one unit and OH unit of the other unit. In such process, water is removed. A. Cystine is formed by the addition of two cysteine molecules via a disulfide bond. Water is removed in disulfide bond formation.
