The rise from being an interesting alternative hypothesis in 1933 to being the leading theory (outside the USA) in 1942 was achieved by a multiplicity of methods. This include:the construction of a new scientific notation, the rationalisation of some seemingly …

WebIt is argued that the S N1/S N2 model of reaction mechanism used by Hughes and Ingold is an example of a fuzzy model, and led to scientific advance at a time when the rival programs, based on classical principles, had stalled owing to problems with the fuzziness of the data. This paper examines a facet of the rise of the Hughes-Ingold Theory of … Web22 mei 2016 · 虽然Thorpe-Ingold 效应的实质还没有完善的理 论来解释,但是应用 Thorpe-Ingold 效应有效地促使 分子内环化,确实是一个很好的方法。. 本文侧重讨 论Thorpe … WebAll those aromatic compounds which are sufficiently reactive to take up the nitronium ion as fast as it is formed from nitric acid obey this law, and, for the same medium and temperature, can be observed to become nitrated at an identical rate, which is simply the rate of formation of the nitronium ion.
