The next six alkanes are named pentane, hexane, heptane, octane, nonane, and decane. Their molecular formulas are CjHij, C5H14, CjHjg, C Hjg and...

Once we have the moleculai fonnula, it can provide infonnation that limits the fflnount of trial-and-eiTor structure writing we have to do. Consider, for exanple, heptane and its moleculai fonnula of CyHig. We know immediately that the moleculai formula belongs to an alkane because it conesponds to C H2 +2-... 

Paraffins are straight or branched chain hydrocarbons having the chemical formula C ii2 +2- The name of each member ends with ane examples are propane, isopentane, and normal heptane (Figure 2-1).

Some new benzanthrone dyes were synthesized and applied for the one-step colouration and stabilization of polystyrene. The chemical structures of monomeric benzanthrone dye (formula 1), the stabilizer TTMP 2,2-(2,2,6,6-tetramethylpiperidine-l-yl)-4,6-dichloro-l,3,5-triazine (formula 2) and the new synthetic product showing both colouration and stabillizer capacity (formula 3) are shown in Fig. 3.135. The synthesis process was controlled by TLC using a silica stationary phase and an n-heptane-acetone (1 1, v/v)... 

CASRN 127-91-3 molecular formula CioHie FW 136.23 ChemicaPPhysical The reported rate constant for the reaction of P pinene with ozone in the gas phase is >9.6 x 10 cm /molecule-sec (Munshi et ah, 1989a). The primary product of this reaction is 6,6-dimethylbicyclo[3.1.1]heptan-2-one (Yokouchi and Ambe, 1989). 

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... 

Draw structural formulas for the isomers of heptane. Name the isomers by the IUPAC system. 

There are nine heptane isomers of formula C7H16. Write structural formulas for each. Name each by the IUPAC system. (In working a problem such as this, proceed systematically by constructing first the heptane, then all the possible hexanes, the pentanes, and so on. Should you inadvertently duplicate a structure, this will become apparent when you name it duplicate names usually are easier to spot than duplicate structures.)... 

Recent studies of the photolysis of bicyclic ketones have led to the preparation of unusually strained systems by the eUmination of carbon monoxide from excited ketone molecules. Irradiation of Formula 286 gives bicydo [2.2.0[hexane (Formula 287) in low yield (118). Mercury-photosensitized decomposition of bicyclo [2.2.1 ]heptan-2-one (Formula 258) gives bicyclo [2.2.1 [hexane (Formula 289) in 20% yield (119). Camphor (Formula 290) undergoes a similar mercury photosensitized decomposition to 1,5,5-trimethylbicyclo [2.2.1 [hexane (Formula 291) (10%) (119). 

Photocyclization of 1,3-cycloheptadienes is a particularly efficient process, since ring fission is not possible. The photocyclization of 1,3-cycloheptadienes in conjunction with a recently developed synthesis of substituted 1,3-cycloheptadienes (159) constitutes an important synthetic entry to the bicyclo[3.2.0]heptane series. Irradiation of 1,3-cycloheptadiene (Formula 361) gives the bicyclic photoisomer (Formula... 

Pinane Group (BicycloQ3.1 JT]heptane Type). Name the pinane-type bicyclic terpene hydrocarbons (bicyclo 3.1.Y beptane type) as pinanes, pinenes, and pina-dienes, and base these names on the recommended fixed numberings of the pinane carbon skeleton (Formula 66, Chart 12). For those derivatives which contain (1) fewer carbon atoms than pinane, (2) the same number as, or more carbon atoms than, pinane but do not have a carbon skeleton identical to that of pinane, or (3) more carbon atoms than pinane and a carbon skeleton identical to that of pinane but contain substituents such that the principle of like treatment of like things will be violated by using the pinane, pinene, and pinadiene names, use the nor- type of terpene names based on systematic bicyclo numbering (Formula 59, Chart 12). See Chart 12.

A class of compounds of the general formula (XIV) can be prepared by two types of reaction the action of the polymethylenedimagnesium dibromide on 1,2-dichlorotetramethyldisilane in tetrahydrofuran, and sodium-potassium condensation of a,a>-bis (chlorodimethylsilyl)alkanes in benzene- -heptane solution (124).
