  • Why is the bond order in the SO₃ molecule 1. 33 and not 2?
    15 $\ce {SO3}$ 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't the bond order be 2?
  • Mechanism of sulfur trioxide reaction with water to make sulfuric acid
    $\ce {SO3}$ is a strong electrophile, enough to react quickly with water, which is a relatively weak nucleophile A water molecule is added to the structure, facilitated by the dislocation of a $\ce {S=O}$ bonding electron pair in $\ce {SO3}$ to the oxygen atom, forming the intermediate structure shown
  • 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 is sulphur trioxide formed and why is it stable?
    Closed 7 years ago Structure of $\ce {SO3}$ (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
  • Why does the conversion of SO₂ to SO₃ require high pressure?
    The conversion of sulfur dioxide to sulfur trioxide in the contact process for the manufacture of sulfuric acid requires the following condition: Temperature: 450 degrees Pressure: 1-2 atm, althoug
  • inorganic chemistry - Separation of sulfur dioxide and sulfur trioxide . . .
    When gases leave the catalytic reactor in the contact process of sulfuric acid generation, both $\\ce{SO2}$ and $\\ce{SO3}$ will be present According to descriptions I have read, the trioxide reacts
  • Is SO3 an ion or a molecule? - Chemistry Stack Exchange
    3 Earlier I thought that $\ce {SO3^ {2-}}$ (sulfite) is an ion with -2 charge but today I read on internet $\ce {SO3}$ (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)
  • 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?
  • 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 Sulfur trioxide a neutral electrophile?
    My chemistry book says, an electrophile is a reagent which is atrracted to electrons, therefore positive ions and reagents with incomplete octets act as electrophiles, Sulfur trioxide belongs to ne
