what do you use methyl methanoate for? seriously. it's moderately toxic. i made some methyl ethanoate about a year ago and while it smells a nice fruity smell, it gives me some bad headaches. altho that could be because i used fuming HCl to catalyze the reaction:\


what's the difference between:





MgO2H2 sort of implies an obscure structure like... Mg-O-O-H2

which obviously wouldnt work. but just saying.


Mg(OH)2 on the other hand shows it perfectly; the Mg makes its 2 bonds with the O from the OH group and each of the O atoms have their second bond incorporated in the H. so everyone's happy

"these generally are the people who obsess over organic peroxides and "francium" which doesnt really exist."


Oh come on, there's about 25 pounds of francium at a time on/in Earth. ;)


Btw, vitamin B-12: C63H88CoN14O14P - the coolest vitamin :cool:

what is a/the purpose of francium other than exploding it?



[edit] or does no one know coz they cant experiment with it? in which case i think, seeing as you obtain it for shor periods of time we should experiment with it.

I know people who trapped Francium. It eventually got away, of course.

what, an hour later?

none. at all. it can be used as a reducing agent but wait, LiAlH4, NaBH4, Li, K, Rb all are more effective. and at high temperatures, carbon works a charm.

"i love organics. there are compounds with names that would go for 3 lines that we chemists would understand and put together. i love it"


Yeah, got to hand it to organics. The 6,6,4-buty-whatever way of marking the structure is especially awesome, like 1-methyl-2,4,6-trinitrobenzene (TNT, C7H5N3O6). :) And the biggest hydrocarbons are cool too (for example C60H122, or hexacontane).

One possible experiment is parity nonconservation. IIRC the weak mixing in the transition from the first excited S state to the ground S state (forbidden under a strictly electric dipole transition) gets stronger as you move down the periodic table' date=' as it has a Z[sup']3[/sup](at least I think it's cubed) dependence.
