A red–black tree is similar in structure to a B-tree of order[note 1] 4‚ where each node can contain between 1 to 3 values and (accordingly) between 2 to 4 child pointers. In such B-tree‚ each node will contain only one value matching the value in a black node of the red–black tree‚ with an optional value before and/or after it in the same node‚ both matching an equivalent red node of the red–black tree. One way to see this equivalence is to "move up" the red nodes in a graphical representation

Synthesis of Benzanilide and Methyl 3-Nitrobenzoate and the Identification of ‘Unknowns’ from Spectroscopic and Physical Properties James Lucas 10394308 23/11/12 Introduction In this series of practicals it was the aim to synthesise both Benzanilide and Methyl 3-Nitrobenzoate. Benzanilide was synthesised using The Schotten Baumann reaction which takes a hydrogen atom from an amino group and substitutes it for an acyl group. For Methyl 3-Nitrobenzoate‚ NO2+ was used as an

Experiment #5: Esterification of Methyl Benzoate from Benzoic Acid October 28‚ 2010 Abstract: This experiment was conducted to synthesize methyl benzoate from benzoic acid and methanol by using the Fischer esterification method. Methanol (12.5ml) and Benzoic acid (4.9 grams) are heated together in the presence of concentrated sulfuric acid (1.5ml) until equilibrium is achieved. A reflux apparatus is set up for 1 hour to carry out the reaction at the boiling point of the solvent (Methanol

the substitution of a proton with a functional group. The electrophilic aromatic substitution reaction nitration is used to nitrate methyl benzoate and acetanilide with a nitronium ion. Crystallization was used to purify the product. The melting point was used to determine its purity and the regiochemistry of the products. The methyl benzoate reaction product‚ methyl nitrobenzoate‚ was determined to be meta-substituted and the acetanilide reaction product‚ nitroacetanilide‚ was determined to be para-substituted

The Grignard Synthesis of 3-methyl-3-heptanol In this experiment‚ an example of an organometallic compound which has a carbon magnesium bond will be utilized to form a tertiary alcohol. Grignard reagents have been extremely useful in the synthesis of a large number of classes of organic functional groups. Although Grignard reagents are unstable and decompose in air and moisture‚ they can be prepared and used immediately with moderate difficulty in the undergraduate organic chemistry laboratory

The Red Panda comes from the family of Ailuridae and its scientific name is Ailurus Fulgens. The Red Fox‚ whose scientific name is Vulpes Vulpes‚ is from the Canidae family. They are both mammals and are the same size. However‚ the Red Panda and the Red Fox share similarities and differences in their appearance‚ habitat‚ diet‚ behaviour‚ reproduction and status of population. First of all‚ the Red Panda and the Red Fox are quite similar but a little different in their appearance. Like the Red

Religious Symbolism in “The Red Shoes†In the Hans Christian Andersen fairy tale “The Red Shoes‚†the color red appears on multiple occasions‚ each time symbolizing something different. The shifts in the meaning of the color can be related to the action in the story‚ and how Karen is feeling or being affected by her surroundings. Karen’s “red and sore ankles†in the opening of the story are the result of wearing wooden shoes in the winter. This redness

What is their field of operation? Red Bull operate within the energy drinks sector of the soft drinks market. The product is an example of a ’functional ’ drink. Functional foods respond to consumer interest in well-being and performance. The major multinational soft drinks companies are investing in the area of functional drinks‚ developing their own brands and buying up existing ones. This is seen as being important‚ given that their traditional soft drinks markets are at the maturity stage in
