The products of the photolysis of cycloheptanone are carbon monoxide, propylene, a hydrocarbon fraction of the molecular formula C Hu (l),and 6-heptenal (31). The hydrocarbon fraction consists of 1-hexene and cyclohexane in the ratio of 1 4.7. A trace of ethylene has also been observed among the products. From a consideration of mass balance, the following reactions may represent the stoichiometry of the photolysis. 

Cyclohexane, the six-carbon ring hydrocarbon with the molecular formula C6H12, is the most significant of the cyclic alkanes. Under ambient conditions it is a clear, volatile, highly flammable liquid. It is manufactured by the hydrogenation of benzene and is used primarily as a raw material for the synthesis of cyclohexanol and cyclohexanone through a liquid-phase oxidation with air in the presence of a dissolved cobalt catalyst.

The properties of cyclohexane, for example, show clearly that it is an alkane. However, combustion analysis and molecular weight determination show its molecular formula to be C5H12. Only a cyclic structure (although not necessarily a six-membered ring) is consistent with both sets of data. 

Similarly, the absorption of only one mole of hydrogen shows that cyclohexane contains only one carbon-carbon double bond yet its molecular formula is which in an open-chain compound would correspond to two carbon-carbon double bonds or one triple bond. Again, only a cyclic structure fits the facts.

Based on elemental composition and relative molecular mass determinations, the formula of benzene was found to be C6H6. The saturated hydrocarbon hexane has the molecular formula C6H14 and therefore it was concluded that benzene was unsaturated. Kekule in 1865 proposed the cyclic structure 4 for benzene in which the carbon atoms were joined by alternate single and double bonds. Certain reactions of benzene, such as the catalytic hydrogenation to cyclohexane, which involves the addition of six hydrogen atoms, confirmed that benzene was a ring compound and that it contained three double bonds. However, since benzene did not undergo addition reactions with HC1 and HBr, it was concluded that these double bonds were different from those in ethene and other unsaturated aliphatic compounds. 

The cycloalkanes are a family having C—C single bonds in a ring structure. They have the general molecular formula QjHjn and thus have two fewer hydrogen atoms than the corresponding alkane (C H2 +2)- The relationship that exists between an alkane and a cycloalkane is shown for hexane and cyclohexane. 

The Kekule structures of benzene account for the molecular formula of benzene and for the number of isomers obtained as a result of substitution. However, they fail to account for the unusual stability of benzene and for the observation that the double bonds of benzene do not undergo the addition reactions characteristic of alkenes. That benzene had a six-membered ring was confirmed in 1901, when Paul Sabatier (Section 4.11) found that the hydrogenation of benzene produced cyclohexane. This, however, still did not solve the puzzle of benzene s structure. 

As before, begin with the largest parent structure (in this case, cyclohexane itself), and work downward in ring size one carbon atom at a time, adding substituents in all possible arrangements to make up the required molecular formula.

Saturated acyciic hydrocarbons have the general molecular formula C 2n 2- Each double bond or ring reduces the number of hydrogen atoms by two as compared with the formula for a saturated compound. Thus each ring or double bond provides one unit of hydrogen deficiency. For example, 1-hexene and cyclohexane have the same molecular formula (C6H12) and they are constitutional isomers. 

Hydrogenation, therefore, allows us to distinguish between rings and double or triple bonds. Consider again two compounds with the molecular formula CsHi2 1-hexene and cyclohexane. 1-Hexene reacts with one molar equivalent of hydrogen to yield hexane under the same oonditions cyclohexane does not react ... 

Two compounds, A and B, have the same molecular formula, CeHa. Both A and B react with two molar equivalents of hydrogen in the presence of platinum to yield cyclohexane. Compound A shows three signals in its broadband decoupled NMR spectrum. Compound B shows only two NMR signals. 

Cycloalkanes contain two fewer hydrogen atoms than an alkane with the same number of carbon atoms. For instance, compare the molecular formulas of cyclohexane (CeHjg) and hexane (C0H14). The general formula of a cycloalkane is...
