Question #19 Gabriel UA Final Review

[Ariel Lucas 1H]

Hi! I was wondering why sulfur (S8) which exists in octahedral form has a bond angle of 104.5. I understand that because it has sp3 hybridization due to two bonds and two lone pairs then the bond angle is less than 109.5, however, is there a way to tell that it is 104.5? Thank you!

I believe for that it's just the found bond angle of Sulfur. For the final, we only need to know that it would be less than 109.5, since we have no way of calculating the exact bond angle of a molecule.
