  • Why is the bond order in the SO₃ molecule 1. 33 and not 2?
    $\\ce{SO3}$ molecule has three double bonded oxygen to the central sulfur atom Sulfur has $\\ce{sp^2}$ hybridization and it has 6 outer electrons which make the bonds with the oxygen So shouldn'
  • Is SO3 an ion or a molecule? - Chemistry Stack Exchange
    Earlier I thought that SOX3X2− S O X 3 X 2 − (sulfite) is an ion with -2 charge but today I read on internet SOX3 S O X 3 (sulfur trioxide) is a molecule with no charge How can this be possible? Please explain knowing that I am only a student of 10th standard (use normal chemistry concepts as far as possible)
  • Is the electrophile in sulfonation of benzene SO3 or SO3H+?
    What's the electrophile in sulfonation of benzene? Is it SOX3 S O X 3 or SOX3HX+ S O X 3 H X +? According to what my professor taught me, both SOX3 S O X 3 and SOX3HX+ S O X 3 H X + may be the electrophile involved - and mechanisms with both species can be successfully written I'm looking for some source (s) that confirms the existence of both electrophiles in sulfonation reaction of benzene
  • Mechanism of sulfur trioxide reaction with water to make sulfuric acid
    Wikipedia says the bonds to all oxygen atoms in sulphur trioxide are equal double bonds In section 2 you seem to have incorrectly started off with the sulphite anion, instead With that correction, does the hydration reaction make more sense to you now?
  • Bents rule for Sulfur trioxide and Sulfur dioxide
    How is Bent's rule applied on $\ce {SO3}$ and $\ce {SO2}$? Bond length of $\ce {SO3}$ < $\ce {SO2}$ Is this a direct consequence of applying the Bent's rule?
  • How to shift SO3 SO2 equilibrium? - Chemistry Stack Exchange
    I am struggling with a chemical equilibrium question and would appreciate some help The question involves a closed system where the equilibrium $$\\ce{2SO2(g) + O2(g) lt;= gt; 2SO3(g)}$$ has been
  • experimental chemistry - Why isnt it commercially suitable to dissolve . . .
    Choose the two correct options from A-F, why isn't it commercially suitable to dissolve $\ce {SO3}$ directly in water to give concentrated sulfuric acid instead of using the contact process?
  • How is sulphur trioxide formed and why is it stable?
    Structure of SOX3 S O X 3 (sulfur trioxide): In the molecule, if each oxygen atom shares two electrons with sulfur atom then how does the sulfur atom remain stable? It already has 6 valence electrons and needs only 2 more to become stable but the oxygen atoms share total of 6 electrons with sulfur atom So how is the molecule stable?
  • How is SO3H added to a benzene ring with two substituents present
    If a benzene ring with an isopropyl group in the first position and bromine in the 3rd position was mixed with SO3 and H2SO4, where would the SO3H attach? Since Br is a deactivating agent that dire
  • Why is the boiling point of SO3 greater than NH3?
    But SO3 has no net dipole as it has a trigonal planar structure, which means that the only intermolecular force that it has are dispersion forces I understand that SO3 has a greater molar mass (80g mol) than NH3 (17g mol), but would this fully explain the difference in boiling point? Especially considering that there are hydrogen bonds in NH3?
