I want to know if a sustained jet fuel burn around steel has the ability to make the steel structurally unsound. It seems like any applied heat that effects steel will be a kind of "heat flash": a sudden, and possibly quite short-lived, burst of heat. In this situation, we assume steel has a melt...

TRE notes and tips Don't edit closed questions! (This is covered with my query, but just in case) The rationale, if you ask, is an SE slogan saying "$\color{red}{\mathcal{don't~polish~turds}}$". Enough said I guess. Don't edit questions that you voted to close/flagged for closure. For the same ...

When comparing o,m,p-toluidine, basicities, ortho effect is stated as a reason why o-toluidine is weaker But, When comparing o,m,p-toluic ccid basicities, ortho effect is stated as a reason why o-toluic acid is stronger acid. Further, I was given the definition that ortho effect is an effect...

How many different organic structures (from the pure theoretical viewpoint) can be drawed with only 4 (exact) carbon atoms and with/without hydrogen? Polycyclic compounds and bridged compounds are also allowed. Please, name them all as well! :) Remark: I have drawed the chemical graphs in a piec...

The Wikipedia structure is: Note the empty bond at far-right. "Journals on the Web" (w/e that is) has: CH3 added at far-right. And rxlist.com shows: There's an extra H going into the page! Is one of these incorrect, or are they all consistent but w/ some implied bonds or something? Ma...

I cannot figure out why glycine hydrochloride is more acidic than chloroacetic acid. Could I have figured this out from a pKa table and maybe am just not seeing it? On the table I have in my book (Organic Chemistry, Seyhan Ege, 3rd ed) , neither acid nor its conjugate base are there. Thanks!

Why does hydroquinone possess non zero dipole moment? The $\ce{OH}$ groups present at para positions on the benzene ring should cancel the effect of each other....if there is a plane change then exactly in which cases molecules do change planes?

Is there any organic compound that has another type of bonds than the covalent bonds?

Could it be electronics? Lone pairs on the two oxygens create an unfavorable environment for approaching nucleophiles and bases. Could it also be sterics?

My professor does not believe in the hyperconjugative effect. Instead, we only consider inductive effects. So do both effects have the same general effect? I know for methyl groups both have the same effect; both hyperconjugation and induction can be invoked to explain the electron donating ten...

If I take a compound like cyclopentadiene (C5H6) and I substitute a nitrogen for a carbon at one of the C = C bonds (making a C = N bond), how does this typically change the hydrophobicity of the compound? The trouble is that I'm not really a chemist. My thought here is that nitrogen is more el...

Is ammonia a nucleophile and hydrogen the electrophile in the B/L acid-base reaction of acietic acid with ammonia? I say that ammonia is the nucleophile because I drew a curved arrow from the lone pair on the ammonia to the ionizable hydrogen on acetic acid, and I drew a curved arrow from the b...

After consulting three organic chemistry texts (Wade, Klein, and Brown), only one actually clearly delineates a few guidelines for picking the most significant resonance structure. The others mention the same factors (maybe less one or two). So in sum, the important factors to consider are: 1) A...

Any idea where to buy chlorinated paraffin for lab application? We need very viscous analog of $\ce{CHCl_3}$. Should we think about synthesizing it? I found a lot of places where I could buy 5 tons:) But we need only few liters for the rest of our life.

When comparing o,m,p-toluidine, basicities, ortho effect is stated as a reason why o-toluidine is weaker But, When comparing o,m,p-toluic ccid basicities, ortho effect is stated as a reason why o-toluic acid is stronger acid. Further, I was given the definition that ortho effect is an effect...

Say for example, the KOH molecule. I know it's a base from literature, but how would one go about determining if a molecule is acidic or basic simply based on the structure of the molecule? How about amphoteric? Also, I understand that there are two complementary systems - Lewis and Bronsted-Low...

I'm wondering why maleic anhydride interacts with the middle cycle of anthracene. My thought concering product based stability: I would have expected that a Diels Alder to the outer ring would be better giving more resonance stabilization because I expected a naphtalene part to be lower in en...

What is the difference in the functioning of alkaline and acidified $\ce{KMnO4}$ as a reagent in organic chemistry? For e.g., in the oxidation of a primary alcohol to carboxylic acid, we use acidified $\ce{KMnO4}$ and not alkaline $\ce{KMnO4}$. Why? Thanks.

What is the final product of this reaction? Here's what I have: Does this look correct? I'm concerned because I'm used to seeing the nitrogen removed from the product (in the cases of primary amines).

It seems that editing posts has recently gone out of control. There is certainly a need for editing and it has always been occurring. In the past it seems like one person at a time was responsible for making 10-15 edits everyday. Now, there are several people doing this throughout the day. Af...
