Chemical environment surrounding the carbons are different and therefore affecting the character of the hydrogens attached. This difference in chemical environment finally explains the different interaction between hydrogen and chlorine. Determination of percent yield, and relative reactivity data was processed after the products of the reaction were analyzed using Gas Chromatography. Percent yield was calculated for each isomer and determined to be; 5.94% for 1,1-dichlorobutane, 23.1% for 1,2-dichlorobutane, 47.1% for 1,3-dichlorobutane, and 23.9% for 1,4-dichlorobutane. The relative reactivity of the hydrogens H1, H2, H3 , and H4 were 0.37, 1.4, 2.9, and 1.0 respectively.
The bond between the fatty acid chain and the glycerol is called an ester linkage. The 3 fatty acids may be identical or they may have different structures. In the fatty acid chains the carbon atoms may have single bonds between them making the lipid saturated. These are usually solid at room temperature and are called fats. If one or more bonds between the carbon atoms are double bonds, the lipid is unsaturated.
Structure of Ethyl Acetate (Toxipedia 2010) | The polar interactions between the solutions and both of the absorbent and the solvent can occur as a dipole-dipole interaction, the result of the contact of two polar molecules with permanent dipoles such as hydrogen bonding and also dipole-induced dipole interaction in which a molecule with a permanent dipole polarizes another molecule. While dipole-dipole interactions are particularly strong, the dipole-induced dipole interactions are much weaker, for instance, Van der Waals interactions (Library 4 Science 2008). These interactions will assist in the determination of the polarity of substances. The compounds provided are Acetaminophen, Acetylsalicylic acid, Ibuprofen, Caffeine and two unknown mixtures. By judging known substances with those unknown it might be possible to determine if any of the known are included in the unknown mixtures due to the different polarity of
Introduction: The radical chlorination of chlorobutane results in the formation of four possible products. These products are formed by substitution reactions, where a halogen atom (chlorine) replaces a hydrogen atom (Wade 2010). The amount of each product formed is based on the relative reactivity of the product. The calculations of the relative reactivity are dependent on the reactivity of the hydrogen atoms, which is influenced by the chloro substituent as well as other factors such as the level of the substituted carbon and the bond dissociation energy. For this lab we want to observe how the chloro substituent has an effect on the reactivity of the possible hydrogen atoms.
Primary and Secondary alcohols can both be oxidized but not to the same extent. Primary alcohols can be oxidized twice as where Secondary alcohols can only be oxidized once. Primary Alcohols can be oxidized to form aldehydes which are the further oxidized to produce Carboxylic Acids: Ethanol Ethanal Ethanoic Acid Secondary Alcohols can be oxidized to form Ketones: Propan-2-ol Propanone Aldehydes a Ketones both contain the same Carbonyl functional group, these similar compounds can be differentiated by using an oxidising agent such as tollens reagent, which when added to an aldehyde will produce a silver mirror. Chemistry of Wine: When wine “goes off” this is an indication that the Ethanol has been oxidized (producing Ethanoic Acid) and other
4. Storage Lipids Pages: 346-358 Difficulty: 2 Ans: B Which of the following statements is true of lipids? A) Many contain fatty acids in ester or amide linkage. B) Most are simply polymers of isoprene. C) Testosterone is an important sphingolipid found in myelin.
If the rate of evaporation is slower, the intermolecular forces are stronger. Alkanes and alcohols are two types of organic compounds in this experiment. The alkanes are pentane and hexane. Aside from carbon and hydrogen atoms, alcohol also contains the -OH function group. The alcohols that were used in this experiment were methanol and ethanol.
Another bottle from the same laboratory is labeled “Compound B (isomer of A).” Compound B also reacts with 1 mol equiv of hydrogen, but yields cyclohexanone after treatment with acidic [pic]. a. Suggest structures for A and B. Answer: b. What was the other product formed in the [pic] oxidation of B?
Isotopes- are atoms of the same element but different number of neutrons. Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are covalent bonds: bond in which one or more pairs of electrons are shared by two atoms.
In this essay I will explain the differences between each of these and how they affect the resulting physical properties of a substance. For example if a substance has a low boiling point and doesn’t conduct electricity, we can tell that it is going to be of simple molecular bonding i.e. covalent. Why Do Atoms Bond? To understand the types of chemical bonding we first need to know why atoms need to bond in the first place.
