I do think I have a good handle on keto-enol tautomerism. If you draw those resonance structures out (de-protonation of A & B), you will see that the conjugated system upon de-protonation of C is still much more extensive because the aldehyde is a Beta-unsaturated aldehyde. I drew these side by...

http://img638.imageshack.us/img638/5747/asdfnt.jpg My workbook says that protons A & B are both more acidic than C, with the answer being A (I do get that A should be more acidic than B). [PLAIN][PLAIN]http://img52.imageshack.us/img52/9800/asdfmi.jpg I chose C though because...

Thanks SC. :)

Thanks very much, SC. Can you take a look at my other thread too? :) https://www.physicsforums.com/showthread.php?t=508743

[PLAIN]http://img543.imageshack.us/img543/4545/asdfrr.jpg I'm wondering what the mechanism would be of the reaction in the pic I've attached. It does seem the Beta carbon acts as a nucleophile and attacks the carboxylic acid. I have a couple of questions, one general (#1) and one specific to...

A question in ExamKrackers asks us why triphenylmethanol is so acidic. Link to the structure below: http://en.wikipedia.org/wiki/Triphenylmethanol Explanation: I'm not seeing how the lone pairs on the Oxygen could donate into any of the rings though. It can't donate those electrons onto the...

Yes, I was talking about n-octane and yes, I meant non-equiv hydrogens. Thanks guys, I guess Kaplan is wrong here.

The answer to my Kaplan test (studying for the DAT, just FYI) says 3, but I think it's 4? Am I wrong?

When you throw in LiAlH4 with a carboxylic acid, you always see the reaction being written out as the Hydride ion attacking the carbonyl function. But why can't it just de-protonate the OH? Also, can't LAH also deprotonate alpha carbons of carbonyl functions that are pretty acidic? Why...

@Yggg: I have another question. How would you write the equilibrium equation? Would you take into account H2O in the denominator or no?

Brilliant, thanks!

According to Zumdahl's textbook, it doesn't. In the book, there is a question that asks which way the equilbrium will shift if additional UO2(s) is added to the system. The answer is the equilibrium is not affected. HOWEVER, I stumbled upon a thread on studentdoctor in which the original...

i know if you push or pull a piston QUICKLY, no heat is transferred (adiabatic process). But what if you push or pull a piston slowly? would heat be transferred in or out if you Push slowly? Pull slowly? why? thanks. i can't find the answer in my book, they just talk about the...
