The Kovats retention index, /, for a linear alkane equals 100 times the number of carbon atoms. For octane, / = 800 and for nonane, 1 = 900. A compound eluted between octane and nonane (Figure 23-7) has a retention index between 800 and 900 computed by the formula... 

One of the most interesting types of polycyclic carbon compounds prepared in recent years is the group of tricyclic substances known as propellanes. A typical example is tricyclo[3.2.2.0 -5]nonane, which sometimes is called [3.2.2]propellane, 12. The physical properties of several of these are included in Table 12-6. A quick look at formula 12 probably does not suggest any great structural difference from the bicyclic compounds we have discussed previously. However, if one tries to construct a ball-and-stick model of 12, one soon concludes that the propellanes are truly extraordinary substances in that all four carbon bonds at the bridgehead carbons extend, not to the comers of a tetrahedron, or even a distorted tetrahedron as for a cyclopropane ring, but...

The next six alkanes are named pentane, hexane, heptane, octane, nonane, and decane. Their molecular formulas are C5HI2, C6H14, C7H16, CaHJg, CjH, and C10H22. The alkanes do not stop at the ten-carbon chain however. Since these first ten represent flammable gases and liquids and most of the derivatives of these... 

Nonane has 9 carbon atoms. What is its chemical formula ... 

The first ten normal alkanes and some of their properties are listed in Table 22.1. Note that all alkanes can be represented by the general formula C H2 +2. For example, nonane, which has nine carbon atoms, is represented by C9H(2x9)+2) or C9H20 Also note from Table 22.1 that the melting points and boiling points increase as the molar masses increase, as we would expect. 

The rapid, acid-catalyzed hydrolysis of the polycyclic phosphite 2,8,9-trioxa-l-phosphaadamantane (L) produces two isomeric hydrolysates, 3-a-oxo-3-fi-hydrido-7-fi-hydroxy-2,4-dioxa-3-phosphahicyclo (3.3.1) nonane (Isomer A), and 3-fi-oxo-3-a-hydrido-7-ff-hydroxy-2,4-dioxa-3-phosphabicyclo (3.3.1) nonane (Isomer B), the configurations of which were tentatively postulated on the basis of infrared and PNMR spectra. Each isomer dehydrates to L under vacuum at 120°C., as well as in the presence of Cu+ or PhiC+ ions to give [CWLJ+ and [P/i3CL]+, respectively. With hydrated metal ions, L forms complexes of the general formula [M(L -HiO)A](X ), where X = BFa or ClOi and M = Mn+, Zn+, Fe+, and Cd+. Of the isomers, only A forms the identical complexes with these ions as well as Ni+. Infrared evidence is presented which is consistent with the postulate that L HiO is an enolform of A bound to the metal through phosphorus. 

You can further condense structural formulas by writing the —CH2— unit in parentheses followed by a subscript to show the number of units, as is done with nonane and decane. 

The meso-(25, 35, 1R, 8R)-tetramethyl derivative (2) of S4 symmetry discussed in Figure 2 is one of seven possible stereoisomers generated by desymme-trization of the original symmetry inherent in the parent spiro [4.4] nonane framework, as shown by the projection formula in Figure 8. 

Another series of polynrers were made from 3,3,5,7,7-I enlanitro-5-aza-l, >-nonane Diisocyanate (IV) and diols. The general formula of polymers is V an[Pg.566]

In Table 21.2, you can see that -CH2- is a repeating unit in the chain of carbon atoms. Note, for example, that pentane has one more -CH2- unit than butane. You can further condense structural formulas by writing the -CH2- unit in parentheses followed by a subscript to show the number of units, as is done with octane, nonane, and decane. 

Nonane is a nine-carbon alkane and has a boiling point of 150.7°C, a flash point of 86°F, a flammable range of 0.8 to 2.9%, and an ignition temperature of 403°F. The structure and molecular formula for pentane are shown in Figure 5.32.

The next six alkanes are named pentane, hexane, heptane, octane, nonane, and decane. Their molecular formulas are C Hjj, C H,4, CjH,. C H , CjHj, and CiqHjj. The alkanes do not stop at the ten-carbon chain however. Since these first ten represent flammable gases and liquids and most of the derivatives of these compounds comprise the vast majority of hazardous materials encountered, we have no need to go any further in the series. The general formula for the alkanes is C Hj ,.2. The letter n stands for the number of carbon atoms in the molecule. The nmnber of hydrogen atoms then becomes two more than twice the number of carbon atoms. Since there is more than one analogous series of hydrocarbons, you must remember that each series is unique the alkanes are defined as the analogous series of saturated hydrocarbons with the general formula C Hj +2. 

Structural isomerisation of a different type was brought to notice by Rabe, Haeuszler and Hochstatter, who have shown that the epicincho-nine of Suszko and Tomanek is not, as these authors supposed, an epimeride of cinchonine, but is represented by formula (H) and the name, /leferocinchonine (/i-cinchonine), has been coined for it. Recently Rabe (1941) has indicated the existence of Aeierodihydrocinchonine and has recorded the occurrence of /leferoquinine in precipitated quinine of commerce. Formula (H) makes these substances derivatives of azadi-cyclo[3 3 2]nonane, which it is proposed to call homoquinuclidine.
