Webby R. Huissgen) Only in the 1918, 25 years too late for Sachse, his theory would be revived and proven correct by Ernst Mohr [J. Prakt. Chem[2] 98, 315 (1918)] based on the X-ray structure of the diamond, which had been determined by Bragg and Bragg in the 1913 using X-ray diffraction. WebApr 8, 2024 · This theory, when published, described the cycloalkane reactivity and its stability in great depths. It also told us that the optimum overlap of atomic orbitals is achieved for a bond angle of 109.50. So in a gist, from this theory, we can conclude that this is the best bond angle for alkanes.

WebNov 21, 2024 · Sachse Mohr's theory is also known as the theory of strain-less rings. It was proposed by Sachse and Mohr in 1918. This theory was explaining the stability of cyclohexane and higher cyclic homologous. In contrast to Bayer’s theory; it assumes that all carbons of the ring are not planar.
