- 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?
- Is SO3 an ion or a molecule? - Chemistry Stack Exchange
For one thing, $\ce {SO3^ {2-}}$ has two extra electrons, so it's an ion $\ce {SO3}$ is a neutral molecule There are a different number of electrons, so they're just different
- 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
- 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
- Is the electrophile in sulfonation of benzene SO3 or SO3H+?
A great deal of work has been done on the mechanism, chiefly by Cerfontain and co-workers Mechanistic study is made difficult by the complicated nature of the solutions Indications are that the electrophile varies with the reagent, though $\ce {SO3}$ is involved in all cases, either free or combined with a carrier
- How to shift SO3 SO2 equilibrium? - Chemistry Stack Exchange
In this case, if I want to decrease the amount of $\ce {SO3}$, I need to shift the equilibrium to the left, meaning that I need to decrease the concentration of $\ce {SO3}$ Based on my understanding of Le Chatelier's principle, changing the temperature will have the opposite effect on the equilibrium because the reaction is exothermic
- Bents rule for Sulfur trioxide and Sulfur dioxide
Here, in $\ce {SO3}$, we have no lone pairs on the sulfur atom whereas, in $\ce {SO2}$, the central atom has a pair of lone electrons According to Bent's rule, the lone pairs tend to occupy the orbital with more s-character which in turn decreases the s-character in the $\ce {S-O}$ bonds and increases the p-character
- Why is the boiling point of SO3 greater than NH3?
$\ce {SO3}$ boiling point is $318 $ K, while $\ce {NH3}$ boils at $240$ K The difference is only $78$ K = $32$ % of the lowest value It is surprisingly low, when considering the difference in molar mass : ($80$ g mol vs $17$ g mol) So $80$ is $4 7$ times higher than $17$ $4 7$ times higher !
