complicated chemistry/world war 1 question?

Question

does any one know the chemical formula for any of these poisonous gases used during WW1?

-Bis(chloromethyl) ether (dichloromethyl ether)
-Ethyldichloroarsine
-N-Ethylcarbazole
-Xylyl bromide
-Methyl chlorosulfonate
-Ethyl iodoacetate
-Bromomethyl ethyl ketone
I need these for a history research project.

Answer 1

Yep, I know them all!

Bis (chloromethyl ether) = Cl-CH2-O-CH2-Cl

Ethyldichloroarsine = Cl-As(Cl)-CH2CH3

N-ethylcarbazole = is a pretty complicated structure, one that can't be drawn in a line notation here. Check out this site: http://www.chemexper.com/index.shtml?main=http://www.chemexper.com/search/cas/86-28-2.html

Xylyl bromide = check here: http://en.wikipedia.org/wiki/Xylyl_bromide

Methyl chlorosulfonate = CH3-OSO2-Cl

Ethyl iodoacetate = CH3CH2-O-C(O)-CH2I

Bromomethyl ethyl ketone = BrCH2-C(O)-CH2CH3

Hope that helps!
