by the way i suck at chem, sorry bud!
yeah it is kewl... but I didn't make it. kudos to the person that did.
I have an answer but I don't know if it's correct or not. I wanted to check with one of the ATOT chemistry geniuses (if there are any).
there are bound to be some chem buffs around here... somewhere!! </dr kliener>
Not a buff, and never got to far with Chem and it's been years but I remember a few things. You are trying to count the convalecent bonds between atoms in a molecule that share the outer shells of P and S electrons right? The question is asking how many carbon atoms, of which there are 26, are making SP bonds right? Or are you suppose to break out which type of bonds based off the shaped of the molecule link you provided? Because if it's the total then the answer is easy. 26. because all the carbon atoms are bonded in the molecule. Duh. As for which type of bonds to form that structure, well that's a different answer. For that you need to look at the connecting hydrogen, carbon, and in the few cases Nitrogen and Oxygen atoms and figure out the overlaps. Since you are sticking with the highest form of orbitals, S and P, looking at that structure should be easy to count since you arenot doing sp3d and sp3d2 orbitals and lower. Then again, I don't see any 5 and 6 groups for sp3d and sp3d2.
If you need to break out the bonds just remember this list.
sp = 2 groups in 180 degree linear bonded electron pairs
sp2 = 3 groups in 120 degree trigonal planar electron bonds
sp3 = 4 groups in 109.5 degree tetrahedral electron bonds. The fourth is usually not on the same plane due to non-bonded electrons.
Then again, I could be remembering jack crap as I'm a computer software programmer these days. I'm not sure if I should give you the answer since part of the fun of chem is figuring it out. I think I gave you the right info to figure it out in about 10 seconds of counting the bonds on the model but as I said I could be wrong.
