heyy everyone i am working on an assignment on s-block elements where all we have to do is basically make notes from our text book ..... i want to make it a...
Hi we did this as part of our AS level chemistry course last year. Group 1 and 2 elements group 1 alkali metals group 2 alkali earth metals ok first ionisation...
heyy paul thanks for the info it was kinda elementary though as i was looking for somthing a little more specific and which would be create some interest .......
Rahul, Something unusual. Hmmm.... Look into the melting points of the alkali metals. The heavier ones are stored in sealed glass ampules, due their...
Hi,Everyone, Happy New Year! Do you study on cyclometallcation of ferrocene derivatives? I would like to dicuss something about that with you. Best wishes, ...
Dear Jon: It goes something like this. In proton spectra (for example) the spin-1/2 nuclei of protons close to the proton under examination shorten the...
Hi to all! It is a very interesting debate the one that there is on chromium and its oxides. However there was always something in the transition series that...
heyy nathan thnkss a lot that was very interesting i looked it up and you were right on the money the mp of Cs is 28.5C if you could think of anything similar...
Rahul, Here is one last item about alkali metals. They are often handled as liquids in laboratory syntheses. Look up the plumbing used to prepare fresh clean...
richard. i had earlier posted regarding copper supposedly more stable I oxidation state tho it is not so.the thing is that copper in it's I oxidation state...
XeF6 has 6bp,1lp. I see many websites or books draw the molecular shape into a octahedral one, if it is so, why does the lp be ignored?? molecular shape: ...

Dear Friends: I shall let this post stand until we can all check it out. Remember that there may be porn, pop-up mania, or credit card traps. If you find any...
Sorry guys. I did not mean that to come out looking like spam. We are creating this new science area entirely pro-bono, there is nothing being bought or sold...
Can I react a enamine with a unsymmertical acyl chloride. will the acyl chloride be able to form a enolate its self and hence undergo a self condensation...
should not be able too because acid chloride is a very reactive species and nucleophilic substitution would probably occurs. Recall that enamineis usually...
... Then how would you go about reacting two alderhydes which are different as self condensation will occur and a mixture of resulting products will occur...
The expression for Q (the canonical Partition Function) is Q = q/N where N is the number of particles and q is the canonical partition of one particle. Can...
hey to prevent self aldol condensation in crossed aldol reaction.we have compounds for thermodyanamin or kinetic control which help in directed aldol...
Xe has 8 s and p electrons available for bonding (which in the ground state form tetrahedral hybrid sp3 orbitals), and so can be octovalent in its highest...
Francisco, Sigma bonds are the chemical bonds between two atoms which allow free rotation about the bond. For example, the bond between the two carbons in...
How to solve( less-more RAPIDLY) suspension of CaCO3 in alkalic water? Ordinar chelates work too slow. Thx, Puk [Non-text portions of this message have...
Hey everyone, I'm a new member of the group, studying in the 11th grade [which as you know is of very high standard in India]. Can someone please explain in...

Can anyone help me with example 8 on the file disconnection I not sure whether I break the bond adjacent to the alderhyde and react formalderhyde with cyclo...
... grade ... Tautomerism is when a proton is moved around a molecule and the structures are linked by equilibrium An example of this is in enols where a...
Ahoy matees! When Rutherford performed his experiment by bombarding Alpha rays on the gold foil , 1. Did he know that Alpha rays were Helium nuclie ,if he did...
