Topic Chemistry/Organic Chemistry:

IUPAC: Melinamide
Molecular Formula: C26H41NO

Question:

How many carbons have sp, sp2, and sp3 hybrid orbitals in this molecule?

JAVA model

Edit:

Solution: so I drew out the structure and did this the long hard way.

There are 15 carbon atoms with sp3 hybrid orbitals.
There are 11 carbon atoms with sp2 hybrid orbitals.
There are 0 carbon atoms with sp hybrid orbitals.

That orbital is pretty cool, made me forget the question. (Not like I knew the answer...)

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>
 
Okay, are you suppose to break up the answer for SP1, sp2 and sp3 hybridization or just total up all the bonds into one number?

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.
 
hrmm looking at the model again, I don't think I see a single sp bond, only sp2 and sp3s. The sp2's are in that funky circle area and of a couple tail ends and the rest are sp3's from what I see. Then again, I could be going blind and I don't want to do a dot chart.
 
easy to count....


draw a lewis dot... all tetrahedral bonded carbons are sp3, all planar double bonded carbons are sp2, and all carbons that have 2 double bonds are sp.
