Organic compounds bond strengths

NBR adhesives can be used at temperatures between 170°C and —40°C. Bond strength can run above 7 MPa and can provide structural bond to many substrates. Even without curing, NBR adhesives show excellent resistance to organic compounds, acids and alkalis.

In Table 2.4, we have collected background information for discussion in the following chapters. Recommended C—H bond dissociation enthalpies of selected organic compounds are reported in the first two columns, followed by a variety of heteroatom-hydrogen bond strengths including N—H, O—H, S—H, Ge—H, and Sn—H bonds. 

We have already noted that the great strength of the 7r-bonds in organic compounds should be regarded as a special attribute of the first-row elements [84AG(E)272 87JST1]. This is evidenced by a comparison between the energies of the C=X bonds (X = C,Si,Ge,Sn) and that of X=X (X = C,Si) (see Table XX). Thus, the 7r-bonds formed by the Si, Ge, and... 

The exceptional thermal and chemical stability of PTFE originate in the strength of its primary chemical bonds. The carbon-fluorine bond energy is the highest currently known among organic compounds [3, 4]. In addition, the fluorine atoms... 

Bonds have characteristic strengths and lengths. Table 13.3 gives the energies of several bonds and the bond lengths in organic compounds.

Compared to other classes of organic compounds, ethers have relatively low toxicities. This characteristic can be attributed to the low reactivity of the C-O-C functional group arising from the high strength of the carbon-oxygen bond. Like diethyl ether, several of the more volatile ethers affect the central nervous system. Hazards other than their toxicities tend to be relatively more important for ethers. These hazards are flammability and formation of explosive peroxides (especially with di-isopropyl ether). 

The compositions and stabilities of organomagnesium derivatives based on different organic compounds have already been considered above. The correlation of the selectivity of cluster insertion with the bond strength in an organic halide or hydrocarbon is quite noticeable.
