Keep in mind that all five of these arrangements have the same chemical formula CeHi4. Compounds that have the same formula, but different structural arrangements, are called isomers. Hexane, for example, is one isomer of C6H14. You will learn more about isomers as you study this chapter. 

Newtonian fluids Fluids that obey Newton s law of viscosity, i.e., fluids in which the shear stress is linearly proportional to the velocity gradient. All gases are considered Newtonian fluids. Examples of Newtonian liquids are water, benzene, ethyl alcohol, hexane, and sugar solutions. All liquids of a simple chemical formula are considered Newtonian fluids. 

Figure 9 Visualize a hydrogen atom removed from a carbon atom on both ends of a hexane chain. The two end carbons form a bond with each other. Describe how the chemical formula changes. 

To complete these steps, we need one additional kind of conversion factor that converts between moles of an element and moles of a compound containing that element. We obtain this conversion factor from the compound s chemical formula. For example, the formula for hexane, C6H14, tells us that each hexane molecule contains six... 

Normal alkanes have the general chemical formula given by C H2 +2. Hence, the total number of atoms is 3n +2 for any alkane defined by the number of carbon atoms (n) in the molecule. The total number of degrees of freedom is 9n + 6. Since all of the alkanes are nonlinear, 9n represents the number of vibrational degrees of freedom per molecule, and these values range from 9 for methane to 54 for n-hexane.

The 100 Most Important Chemical Compounds focuses on 100 compounds, but references several hundred compounds. Structures and formula for compounds other than the 100 are included in the entries and listed in the index. Repetition of information was kept to a minimum by including representative compounds or the simplest compound in a chemical family and highlighting chemical properties that distinguish chemical groups. For example, there are entries for methane, ethane, butane, and octane but other alkanes such as pentane, hexane, and heptane are not included. Most personal names in the book include years of birth and... 

BASIC PROTOCOL I PREPARATION OF FATTY ACID METHYL ESTERS FROM LIPID SAMPLES CATALYZED WITH BORON TRIFLUORIDE IN METHANOL In this method, lipid samples are first saponified with an excess of NaOH in methanol. Liberated fatty acids are then methylated in the presence of BF3 in methanol. The resulting fatty acid methyl esters (FAMEs) are extracted with an organic solvent (isooctane or hexane), and then sealed in GC sample vials for analysis. Because of the acidic condition and high temperature (100°C) used in the process, isomerization will occur to those fatty acids containing conjugated dienes, such as in dairy and ruminant meat products, that contain conjugated linoleic acids (CLA). If CLA isomers are of interest in the analysis, Basic Protocol 2 or the Alternate Protocol should be used instead. Based on experience, this method underestimates the amount of the naturally occurring cis-9, trans-11 CLA isomer by -10%. The formulas for the chemical reactions involved in this protocol are outlined in Equation D1.2.1 Saponification RCOO-R + NaOH, RCOO-Na + R -OH v 100°C DC Esterification RCOO-Na + CH,OH r 3 v RCOO-CH, + NaOH ioo°c ... 

The electron acceptor numbers (AN) can be used as a measure solvent ability to take a share in the electron pairs from suitable donors. They are defined by means of a different experimental procedure on the basis of the NMR chemical shifts of phosphorous which are produced on transfer of EtsPO through solvents. AN values are scaled from an arbitrarily chosen value of zero for the shift produced by hexane (or 1,2-dichloroethane) to one hundred for the shift produced by the 1 1 EtsPO—SbCls adduct in 1,2-dichloroethane. An estimation of the coordinate bond energy is possible by making use of the formula after Gutmann [155]... 

If you know the vapor pressure exerted by a specific chemical, you can calculate its partial pressure on the various trays. Figure 19-2 illustrates the partial pressure principle. For example, a mixture of hexane 25%, benzene 50%, and heptane 25% will exert a specific pressure at 175°F. To calculate the partial pressure, use the formula ... 

Straight-chain or branched chain compounds that contain a C=C double bond are different kinds of hexanes. A hexagon-shaped ring of C Hj is called cyclohexane. Rings with the formula C Hj do not contain a double bond. All of the different compounds of CgH have their own chemical and physical properties. 

Two or more compounds that have the same molecular formula but different molecular structures are called isomers. The two main classes of isomers are structural isomers and stereoisomers. Structural isomers differ in the order in which atoms are bonded to each other. For example, hexane, 2-methylpentane, and 3-methylpentane are structural isomers because they all have the molecular formula CgHj, but they have different carbon chains. Structural isomers have different physical and chemical properties.
