Mr.Chemist

I recommend this site, http://www.orgsyn.org/ , when you want to find reliable method to synthesis some substance.

thank you....

thank you very much for these useful resources. may i ask if ethanol really is a catalyst in nitration of toluene? i can't find the answer on the net. maybe you can help me please? urgent please. thank you...

Hi I'm Mc from Philippines.

kindly read about photosynthesis specifically electron transfer. When there is an electron flow, electricity is produced. Check about Coulumb's Law. You can make a very sophisticated 'machine' to make use of that very low electricity.

hahaha

From what the product of 'theoretical ammonium hydroxide' and aluminum are, to the debate whether ammonium hydroxide exists or not. Haha. It's actually not with the name. It is the reaction of ammonia and water that there is a production of ammonium ion and hydroxide ion (though some part of the hydroxide ion production is due to ionization of water itself). OF course both ions exist but as I have said it is not with the name. There is no such evidence that ammonium ion clings to the hydroxide ion. They coexist in solution. In the question whether what would be the product, I haven't tried putting aluminum to ammonia solution. But most probably, aluminum hydroxide will be produced (I just don't know if it would really take years).

Photosynthesis really creates electrical energy but of extremely low quantity. It's in the process of electron-transfer. I guess what you are saying as a suitable apparatus is quite far from realization that it's only you who have thought of using plat as an electricity source but who know. Maybe in two or three scores, you'll be able to make that suitable apparatus. Nevertheless, your idea is good. Thumbs up. Only few can think the way you thought. I admit, even I can't.

Start here.

Then google 'millons test'. Start by reading the (very short) wiki article, and then from what you learn there google some of the key words and see if you can't work out its importance on your own. If you get stuck i'll give you some more help.

 

THank you!

yes please. also i have this question on the importance of millon's test and the reactions it has.

I really have a little difficulty on this topic 'Synthesis of Organic Compound from alkyne and alkene'. I need some help please. I would like to know about the rules on how you can get either aldehyde or carboxylic acid, ketone or what. Thank you.

This would greatly help. Thank you missgeek and suxamethonium.... I will choose one from them missgeek as my classroom demo.

Howdy? I'm looking for something unusual that I can do in my classroom demonstration in Chemistry. I have one problem though. I don't know what to do. Who has an idea of a really cool and interesting experiment? The ones which use chemicals that are common and safe. Thank you for considering.

Um, so there is a lot to address in this post. Firstly, the alcohols you listed.

 

Ethanol (EtOH) is a primary alcohol, as is n-butanol (nBuOH). Sec-butanol (sBuOH) is a secondary alcohol and tert- butanol (tBuOH) is a tertiary alcohol. benzene alcohol? Possibly benzyl alcohol or phenol- either way representing aromatic alcohols. Methyl chloride is obviously not an alcohol.

 

The lucas test rarely works for primary alcohols (very very slow), is slow (15 mins) for secondary alcohols and is relatively fast for tertiary alcohols. The chromic acid test will react with primary and secondary alcohols but not tertiary. The iodoform test is for methyl ketones (RCOMe). I do not know of the methanol test.

 

Solubility: Generally as the chain length increases the alcohol becomes less soluble in water.

 

As for testing for chlorides, we used to clean the copper wire, flame it and then dip it in the sample and reflame. If the flame was greenish a halogen was present.

yah, it's benzyl alcohol... thank you for clarifying things to me. I really have to learn a lot of things about organic chemicals.

Good day! I am an undergraduate student and one of my subjects is organic chemistry. It was really a challenging subject especially when we do the laboratory experiments. One experiment is testing for alcohols. We used ethanol, n-butanol,sec-butanol,tert-butanol, benzene alcohol, and methyl chloride. I tried to read discussions about these lucas test, chromic acid test, iodoform test, and methyl alcohol test but i can't fully grasp the material. Can you please help me about the solubility of the alcohols to water? How about the reactivity of the primary, secondary, and tertiary alcohols? Did my teacher get it correctly that when we dip a hot copper wire, only the oxygen is being transferred into the methyl chloride not the CuO itself? Thank you.
