Drawing the structure

Postby Bao Tram Nguyen » Sun Oct 27, 2019 1:11 am

So in class on friday we talked about how to draw a structure for CH5 and it looked like a pentagon with a circle inside it. Would count as a lewis structure or what would you call it?

I think it is still a Lewis structure because it shows electrons being shared between atoms.

Yes, it is still a Lewis structure even though P breaks the octet rule because it uses the same notation (lines for bonds and dots for valence electrons) as other Lewis structures.

It is still considered a Lewis Dot diagram approach for the electron configuration but Phosphorus is a special case

It's still a Lewis Structure, just seems different because Phosphorus is capable of having an expanded octet

Yes, it is a Lewis structure and P is able to extend the octet because it is in the d-block.

Just be sure to know which elements are able to expand their octet so it doesn't mess up your lewis structure or cause confusion.

That shape is the resonance hybrid and it depicts the bond length as relatively equal rather than some being stronger than others. For example, the c-c single bond in benzene has a length of 1.54 Angstroms while the c=c double bond in benzene has a length of 1.34 Angstroms. Experimentally, however, each of the c-c bonds are 1.39 Angstroms.
