Web21 apr. 2015 · The simplest correct explanation is as you say, simply having three sigma bonds, one pi bond and two ionic interactions, giving a bonding order of 1.33. Invoking d-orbitals is unnecessary. – J. LS Apr 21, 2015 at 10:31 Fair enough, I agree, it's a bit of fluff that I carried over. I will edit the answer to reflect that! – Adam Kewley Web1.1 WHAT ARE SULFUR TRIOXIDE AND SULFURIC ACID? Sulfur trioxide is generally a colorless liquid but can also exist as ice- or fiber-like crystals or as a gas. When sulfur trioxide is exposed to air, it rapidly takes up water and gives off white fumes. It combines with water, releasing considerable heat while forming sulfuric acid. WebIn sulfonation reaction, the electrophilic species which is sulfur trioxide substitutes the proton of the aromatic compound leading to the formation of aromatic sulfonic acid. Fuming concentrated sulfuric acid is a solution of sulfuric acid, water, and the as required electrophile for the sulfonation reaction, sulfur trioxide. fnaf cheats 1
