A Lewis structure is a two-dimensional representation of a molecule that does no

Question

A Lewis structure is a two-dimensional representation of a molecule that does not necessarily show what shape that molecule would take in three dimensions.

?From the following Lewis structure and what you know about VSEPR theory, approximate the smallest bond angle in this molecule

I tried 109.5 before and 100

Explanation / Answer

Answer:  That's it. There is no way to determine the exact number. At the very best, you can say that the lone pairs will cause some distortion, resulting in a bond angle less than the hypothetical 109.5 degrees associated with tetrahedral electron pair geometry.

For instance in the case of water, H2O, the bond angle is about 105 degrees. in the case of hydrogen sulfide, H2S, the bond angle is 92 degrees. The bond angle could be anywhere from 109.5 to 90 degrees and even less.
