Lewis Diagrams Made Easy: How to Draw Lewis Dot Structures

[@christianmccauley7340]

The worst part is my chem teacher is s o great like, as a dude. He’s passionate about what he teaches and you’d think that would make it more interesting, and I guess it does, but it’s really hard to make chemistry interactive. He does his best on that by bringing the class into interactive demonstrations using the students as a way to engage and help understand a little better, but it’s just not enough that the class can feel droning. It’s not like he can condense the work, it’s an hour an ten minute class. Over all I actually love him, easily one of my favorite science teachers, but chemistry teachers gets a bad rap because it’s just so un-engaging.

Just in case you have seen the Lewis diagram of sulfur trioxide as something different (i.e. three double bonds as shown in Wikipedia or some old books), current theory suggests that the simple Lewis diagram I drew is most correct based on the lack of d-orbital participation in bonding and the calculated charges (sulfur is positive and oxygens are negative as predicted from formal charges).

Not just hydrogen, but also Li+ , Be2+ and Helium violate the octet rule bcz they can't have 8 electrons in their valance shell. Other elements that violate octet rule are transition and post transition elements, which contain more than 8 electrons in their valance shell.

As one who also teaches this example in a way that arrives at the same dot structure, I bristle at those who show more than one pi bond at an sp2 hybridized atom.

[@yahya3898]

I don't get how the two Oxygens with a single bond have 3 lone pairs AND a bond. Since oxygen has 6 electrons on the outer shell and a bond, would those single bonds count as dative (where both electrons come from Sulphur)?

[@ketzbook]

I advise against thinking about where the electrons "came from". Yes, you could think of it as dative, but it is better to look at the molecule as a whole. The molecule has a certain number of electrons, and we put the electrons in as bonds or lone pairs to give every element an octet if possible. In the ion hydroxide, oxygen has 3 lone pairs and one single bond, and that bond is definitely not dative. In any case, this leaves oxygen with a -1 formal charge, which supported by high level calculations on the SO3 molecule that shows the oxygens have some negative charge.

[@yahya3898]

ketzbook I understand, thanks. Really been scratching my head over this for the past two hours.

[@yahya3898]

The only reason why I wonder where the electrons came from is dot and cross diagrams. These questions I'm doing ask for both, Lewis diagrams and dot and cross diagrams.

[@ketzbook]

Oh. I'm not a fan of dot and cross diagrams, so I don't ask my students to do them. In that case, you could just say that both electrons come from sulfur.

[@yahya3898]

ketzbook Very helpful, much appreciated :)

[@rizuna]

SO3 is wrong, oxygen only has 6 valence electrons, and in the lewis structure you showed it has 7 also you calculated that there are 18 valence electrons, how come there are more than 18 v.e’s in your lewis structure?

[@Al-Suzuki]

Exactly, it’s actually a resonance, and Oxygen will have only 4 lone Paris electrons with its double bond and the other two oxygen with one bond will have 5 lone pairs. Am I right?
