AI Thread Summary
The discussion centers on the hybridization of boron compounds, specifically questioning the existence of a compound with the formula BO3-. Participants clarify that the correct hybridization for boron in certain compounds is sp² rather than sp, and they emphasize the importance of accurately drawing the Lewis structure to determine bond pairs and lone pairs. Sodium perborate is mentioned as an example of a compound containing boron, highlighting that not all theoretical formulas correspond to stable compounds. The conversation also touches on the distinction between chemical and empirical formulas, suggesting that BO3- may not be a common species. Accurate understanding of hybridization and molecular structure is crucial for determining the existence of boron compounds.

Homework Statement
The question asked the hybridisation and shape of ##BO_3^-##
Relevant Equations
N=##(X+Y-C+A)/2##
where C is positive charge on the compound
A is negative charge on the compound
X is valence electrons of central atom
Y is no. of univalent side atoms.
If N=2,then sp.
One would easily calculate its hybridisation by the above formula which comes out to be sp.
But my doubt is that will the compound even exist?As boron will become electron deficient and how we will calculate no. of bond pairs and lone pairs.Please clear my doubt.

Have you tried to draw the lewis structure??

yes not able to draw it,that's why i asked here.

If your doubt is only the existence, there's sodium perborate. Check your notes and the formula because there isn't a sp Boron in the lewis structure of such compound

Thanks i got it.It's ##sp^2## hybridised and i think it is planar too isn't it?

I don't think is planar, the boron has more character $$sp^3$$... nevertheless you can check it out with the lewis structure in the internet and do an analysis (bond order, paired and unpaired electrons, etc)

I don't think BO3- exists or if it does, it is not a very common species. [BO3]3- does exist, however. Perhaps you can clarify with your instructor if BO3- is the correct formula.
 
Ha ha! Formula for perborate this is...
Chemical formula is not the same as empirical formula. Tricksy, tricksy!
