WebBorane is thus a Lewis acid. Figure 2. Lewis dot structure of borane. Since the phosphorous in triphenylphosphine has a filled orbital and the boron of borane has an empty orbital, a Lewis acid-base adduct can form, with the triphenylphosphine donating its two electrons to boron. http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch11/lewis.php 3b meteo buisson WebGilbert Newton Lewis ForMemRS (October 23 or October 25, 1875 – March 23, 1946) was an American physical chemist and a dean of the College of Chemistry at University of California, Berkeley.
