Highest density Organic Fuel?!
Hello all! What’s the highest density organic fuel (solid or liquid).
The best I could find was amino-guanidine, semicarbazide, and Urazine.

Iodoform.
Lousy fuel, but very dense

If you mean as a bipropellant, reacting with air oxygen, and considering the heat of combustion per unit volume, I'm going with cubane.
Heat of combustion 4833 kJ/mol, density 1.29/H2O, molar mass 104.15 gives a whopping 59.86 MJ/L, compare diesel at about 37 MJ/L or LiBH4 at 44 MJ/L.
Of course, if you consider solid carbon an "organic fuel", its energy density is even higher at around 75 MJ/L.

CD4, but you'd have to get it really hot to get that energy out. (fission based primer)
Organouranium 235 compounds would be less energetic, but still have quite a kick.
I have no Idea if they'd work in a bomb, but they sure ought to work in a reactor.
I'm assuming you mean highest energy density.
Looks like Unionized answered the question you actually asked.
Edit: Solid carbon? Organic? Clearly not, Atara!
No carbon hydrogen bonds.

Hexaiodobenzene, 4.6.
Maybe make that pentaiodobenzoic acid salted with a heavy metal.

If that counts, I say antimatter. 50 megatons per kg, don't bother calculating the joules, you know it's a lot.

A bit more digging leads to
https://en.wikipedia.org/wiki/Hexaiodobenzene
There may be denser options.

Yup, but making organic molecules out of antimatter would be pretty tough.
Sigma Aldrich sells CD4 by the liter.
How would one go about making anticarbon?

All. Thank you for the responses! I should clarify my question. It would be for a scram jet, so all atoms would have to be active, or mostly. Iodine
would be dead weight, and antimatter, we’ll give me a ring when you figure it out 
The important thing would be for the combustion to be gaseous, no metals. I am now thinking that graphite or, despite it not being practical diamond?!
Semicarbazide and Urazine are still very dense. It seems cubane would be a winner as well, tho that is even less practical than diamonds do to the
cost?!

What is CD4?

Deuterated methane.
Obviously not scramjet fuel though.
And the carbon would be dead weight. I just though the idea of an organic fuel for a nuclear reaction was amusing.
