what's the difference between:

 

MgO2H2

&

Mg(OH)2

 

?

CH3COCH3

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

&

Mg(OH)2

?

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

[MulderMan]

its acetone last time i checked. isnt methyl methanoate C2H4O2?

[budullewraagh]

yes, yes it is. i read that incorrectly. disclaimer: i had just woke up

 

you had methyl ethyl ether. ok. im going to go take a shower and wake myself up right about now

[MulderMan]

no probs lol, i had to google methyl methanoate anyway!

[budullewraagh]

yeah, that second C looked like an O

 

im really cool!

"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

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

 

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

[5614]

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.

[budullewraagh]

what, an hour later?

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

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.

[Gilded]

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

 

Yeah, I recall some people trapping it quite a bit.

Oh, has someone mentioned aspirin (acetylsalicylic acid)? It's C9H8O4.

[budullewraagh]

augh. i hate it when i see organics written in that format:\

i know im guilty myself...

 

btw suny stonybrook...thats in MY state.

swootle

[MulderMan]

ill take Acetaminophen!

 

erm i would say C5H5NO2 but seen as though its you - Methyl 2-Cyanoacrylate

[Gilded]

What if people said more what the molecular formulas actually mean in English - that would be nice. (Of course, only in cases where the compound actually has a shorter/simplier everyday name)

[budullewraagh]

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

[Gilded]

"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).

[MulderMan]

would confuse the normal people, but after all we do call ourselves scientists! and cyanoacrylate is pretty well known...

[budullewraagh]

1-methyl-2,4,6-trinitrobenzene

come now, thats just called 2,4,6 nitrotoluene

[jdurg]

come now, thats just called 2,4,6 nitrotoluene

 

Actually, the proper term would be 2-4-6-trinitrotoluene.

[budullewraagh]

1-methyl-2,4,6-trinitrobenzene; 2,4,6-Trinitrotoluene; 2-methyl-1,3,5-trinitrobenzene; alpha-trinitrotoluol; entsufon; methyltrinitrobenzene; s-trinitrotoluene; s-trinitrotoluol; sym-trinitrotoluene; sym-trinitrotoluol; TNT; tolite; trilit; Trinitrotoluene; Trinitrotoluene, 2,4,6- ; trinitrotoluol; trotyl;

You want to do it the easy way, or you want to do it the hard way?

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.
