With two reagents common on Mars, fluorite and CO2, how would I produce carbon tetrafluoride?
The hypothetical terraforming of Mars would require the heating of the atmosphere. A commonly suggested method is the in-situ production of fluorocarbons, powerful greenhouse gases.
For example, ...

Has tellurium(II) iodide been properly characterized ever?
According to Wikipedia, tellurium tetraiodide decomposes on heating:
$$\ce{TeI4 ->[\Delta] TeI2 + I2}$$
However, the reaction is somewhat wrong as according to this 2008 paper:
Solid tellurium ...

Why is ammonium chloride rather than an alkylammonium chloride salt the product of nucleophilic substitution of a chloroalkane by ammonia?
My textbook said that when an excess of ethanolic ammonia is heated with a haloalkane ($\ce{R-X}$) one should give the products as being $\ce{R-NH2}$ and $\ce{NH4Cl}$ as opposed to $\ce{RNH3Cl}$. I ...

How to get (2R,3R)-2,3-dibromobutane from but-2-yne?
What I had in mind was to form but-2-ene with $\ce{H2}$ and Lindlar's catalyst and then simply add bromine ($\ce{Br2}$). But this addition, if I'm not mistaken, is a trans-addition. So I would end up ...
