Heelo guys, I am a new member of this group. This group looks great. I have one question. Why when benzene attached to activating group or electron donating...
Hello fellow chemists! I just joined the group in time to get involved in a controversy. There is an excellent review by Kornblum of the reaction of alkyl ...
In the first conversion i.e. 2-methylpropan-2-ol to 2-methylpropane, what if I turn it into the 2-methylpropan-2-oic acid by reaction with aqueos KMnO4,...
Dear Munro: First, I don't think that 2-methyl-2-propanol reacts with KMnO4. Second, if you somehow get to 2-methylpropanoic acid and decarboxylate that, you...
... great. ... Hi Handarmin! The reason is that the intermediate positive ion can distribute the positive charge among more of its atoms by resonance in case...
Hi, Can anybody help ? I need to know all possible methods for copper etching. Innovative suggestions are welcome ... Best regards, -- Suman Chakrabarty ...
When benzene is attached to an electron donating grp. like -OH (phenol) the o- and p- positions become electron rich due to the electronic effect and the...
Those 1962 and 1963 Kornblum references date from more than 20 years before T.W. Solomons' Organic Chemistry (1984), which I quoted in support of my view of...
2-methylpropan-2-oic acid cannot exist! 2-methylpropan-2-ol, which is, in fact, tert-butanol, or trimethylmethanol, is a tertiary alcohol. Only primary...
"anus features" is obviously just a troll. My understanding that copper etching, e.g. to produce bronze or brass engraved plaques, is done firstly by masking...
Hello Friends,
This time I have a new and very cool website to recommend: http://www.cgmoore.com.

Hi everyone, I am new here. I am enrolled in an organic chemistry class that is via the internet. I have to devise an experiment that will compare the...
... ********** I'm NOT sure about alcohol. While heating, it'd evaporate and hence, mass of the system will vary. So, temperature is not the only variable...
... copper ... Why not just use commercially available solution of Ferric Chloride as this is the industry standard method. Ferric Chloride solution is less...
... ********* Can you elaborate a bit please ?! What is the chemistry behind ? As far as I know, copper can't replace iron from ferric chloride. Then how come...
Stop with the flames. Youve got your sheet of copper pcb, basically your draw your circuits using a 'dalo' pen, which is some sort of special ink. You then...
I have never heard of Cu or its alloys dissolving in FeCl3 solution before, and this being used to etch Cu or its alloys - especially as Fe, along with H, is...
Much too dangerous. Ethanol has a normal boiling-point of only around 79șC, and the flash-point of ethanol vapor/air mixtures, which can explosively ignite in...
Dear Friends (I especially speak to friends JohnWW and Sarah Murray): The ChemistryCluster is a target for spammers, advertisers, and evil- doers. As soon as I...
Steve this is Estrellita, I was trying to talk with you earlier about lead poisioning, my daughter's test was high, it sure is a mystery to me, because my...

As well as old PbO white paint being sanded off houses, it could also come from exposure to colored paints, especially primers, containing "red lead" (Pb3O4),...
Dear Estrellita: As JohnWW points out, the usual source of lead poisoning in children was house paints. Children in poor neighborhoods with decrepit housing...
Dear Estrellita: I urge you to get to the bottom of your children's lead levels. If one child is "high" and the other child "not," then something funny is...

Another approach to anti-knocking, to replace Pb(C2H5)4, is the replacement of part, usually up to 10%, of the gasoline with ethanol or methanol (more than...
will u plz tell in detail : 1]is CCl4 and CO2 is a organic or inorganic? 2]how can we distinguish the organic and inorganic compounds by practicle and theory?...
T.W.G. Solomons' "Organic Chemistry" 3rd ed. 1984 says, in his opening statement on page 1, that "Organic chemistry is the study of the compounds of carbon"....
