Why are sp2 carbons more downfield than sp3 carbons? Is it because the bond length of sp2 carbons is shorter (electrons are more localized-thus more shielded)?
Hi, I am trying to understanding how esters can form a cyclic alkane. Could someone explain the mechanism for this? I would guess that we'd have to hydrolyze the ester in acidic condition to carboxylic acid. The hydroxide then can attack the carbonyl to form a ring, but that would give us an...
In the lab, can the reaction form a mixture of aldehyde, carboxylic acid, and alcohol? What I mean is that could some of the aldehyde may not have reacted and be present in the product maybe because too much is used? Or is the reaction exclusively yields an alcohol and carboxylic in equal...
I would think that axiom 4 is not satisfied.
if u=(1,2) and v=(2,2), then -u2v2=-4, which is less than 0, which violates axiom 4 that states (v,v) greater than or equal to 0. Is this right?
Homework Statement
State why (u,v) is not an inner product for u=(u1,u2) and v=(v1,v2) in R2
(u,v)=-u2v2
Homework Equations
(u,v)=(v,u)
c(u,v)=(cu,v)
(v,v)=>0 and (v,v)=0 if only if v=0
The Attempt at a Solution
I am having trouble understanding this problem and how to start it...
Why do we have to redissolve the product we get from the reaction of cyclopentadiene with maleic anhydride? Is it to remove the impurities? The endo-norbornene-5,6-cis-dicarboxylic anhydride product I got from the reaction after the second recrystallization had a melting point 24 degrees lower...
Why does delocalization of the negative charge over the ortho and para positions of aromatic rings increase the stability of the phenoxide anion? Why do the ortho and para positions increase the stability but not the meta position? Please explain. Thank you.
If you dehyrate 1-butanol, wouldn't you get 2-butene due to rearrangement? This is not a homework question. This is an mcat review question. The question asks: when 1-butanol is dehydrated, the new compound's heat of hydrogenation is most likely? The answer is between 30 and 33 kcal/mol
It...
What is the point of adding the sodium dichromate dehydrate in water solution dropwise to benzhydrol in glacial acetic acid? Why can't we just add it all in at once? Also, what is the purpse of the glacial acetic acid?
After we got the solid from the reaction of benzophenone with sodium borohydride, then we dissolved the solid in a minimum amount of hot methanol. Why do we add the same amount of water to get the resulting solution to a cloudy point?
so does heptet mean multiplet? Why do sometimes you see textbook uses sextet, heptet, ... and not multiplet? This is what confuses me. When do you use sextet, heptet,... and multiplet? Please give an example. This would clarify things a lot. Thank you.
