<p>don’t even sweat the quizzes for 1b. lab is worth next to nothing (okay well a little more than that) but 1b is all about midterms and finals in the end really since labs are all averaged out to 85% or some bs anyways.
it’s what happened to me in 3a. i kept worrying about 1b that i never really studied for 3a and I still ended up with a B+ because I messed up badly on Feldman’s. Made the final mah ***** though. lol</p>
<p>wait so the last lecture isn’t gonna be on the test???</p>
<p>lecs 1-11 on the test</p>
<p>wow gg i just spend the last hour studying acid/base with carbonyls…</p>
<p>Imma drink 3 monster shots IN ONE HOUR. I’ll be the jittery one in Pimentel. They should let me listen to music while taking the test. I would ace it while feeling pumped up.</p>
<p>how does 142 d happen? is it just negative charge takes allylic hydrogen? que da f.</p>
<p>that anion acts like a really strong baes</p>
<p>so for 182, the first one has carbon as sp3 right because of geometric reasons (is that the correct reasoning?)</p>
<p>:( didn’t do that hot</p>
<p>I don’t know…besides that Iodine mechanism and that Diels-Alder with nitrogens It seemed pretty easy. I’m feeling that the curve will be non-existent. What did you guys get for the lycopene? Talking to my friends it seems to vary from 20 something to 40 something with everybody having something different.</p>
<p>Should be 22…or that’s what i got. i *<strong><em>ed up major on predict the products…too scared to do stereocenters. that’s such a </em></strong>. I don’t know, it wasn’t terrible, but it wasn’t great either.</p>
<p>i said 22, 11 bonding 11 antibonding</p>
<p>and yeah idk about that iodine, i just put it in, made it trans, then took it out… lol</p>
<p>i said excess h2, pd/c for the lycopene reactant thing is that right?</p>
<p>that’s wut i put</p>
<p>calbear got an A, u heard it here first</p>
<p>calbear probably did. he/she was answering all our questions with ease other you too Mech. I’m sweating at the predict the products. I hate the miss one cancels right one so much right now. I wanted to just rip my test up in anger. **** stereochem</p>
<p>Hahaha whatever! I wasn’t so sure about my answer on the Diels-Alder rxn on the last page.</p>
<p>i don’t think i put more than 2 products for anything except 3 for the NBS thing</p>
<p>was it 2 products for the last page diels alder?</p>
<p>i got 4 for the h2so4 with OH…</p>
<p>harder than 3A exams (which doesn’t really say much)…but overall it wasn’t too bad</p>
<p>22,11,0</p>
<p>uh…h2, pd/c do make it colorless?</p>
<p>god damned molecules of the day…</p>
<p>ya. i might have put nbs along with it =
makes it colorless because it takes away double bonds</p>
<p>Yeah I put H2 with pd/c because using the equation he gave us energy is inversely proportional to wavelength so less conjugated systems are higher in energy hence have a shorter wavelength absorption so they become colorless. IDK I kinda wished he didn’t put “same number of carbons” because that was kinda a dead give away.</p>
