<p>Just an experimental detail I believe.</p>
<p>So how do you know if a ring is conjugated if it is a charged ring? like i’m looking at 140 B and I thought the diene with the minus charge (second row third molecule) would be completely conjugated…</p>
<p>the upper right corner of that molecule (right of the - charge) is sp3 hybridized so it can’t be</p>
<p>oh gg i completely ignored that one. these small mistakes are gonna kill me. and that one guy today was saying pederson is pretty anal about grading. bruha</p>
<p>are there office hours today?</p>
<p>I think I see what calbears was saying and now I’m confused too. Looking at 323 C1, so if N has a double bond and a single bond then the lone pair isn’t counted in Huckel’s Rule I take it?</p>
<p>I don’t think there’s OH on weekends…? Could maybe try emailing the BHS …</p>
<p>i don’t think it’s counted in that case</p>
<p>ok. I hate how I keep asking questions but in your original problem, does it matter where the methyl group sticking out ends up in the product? Because I keep getting it in different places like in 31 C for example…his methyl group sticks out where the benzene connects with the hexane. But mine is like 1 C away from the connected spot</p>
<p>that is a result of hydride shift, you get the product in the answer key when you do it</p>
<p>Would it be wrong though?</p>
<p>yeah lol (10 char)</p>
<p>ok another question on 72 b, i switched the order of the reagents. would that be wrong?
and is it just because the hydride shift makes it more stable?</p>
<p>yeah i think that would be wrong</p>
<p>and yup</p>
<p>ok so do you know why bromination needs to come first?</p>
<p>NO2 is a meta director. if you did it your way, i think it would probably go para (the bromination)</p>
<p>thanks so much for your help mech…lol i’m still on problem set 5 how’s your studying going?</p>
<p>no problem bro, i’m on #5 too, diazonium ion chemistry</p>
<p>i’m gonna skip all my classes tomorrow to study for this =/</p>
<p>i might do that, but i have physics discussion tomorrow and i feel like I need to go to that…
but question, for 298 B, it’s an intramolecule EAS, but I thought NC- groups were meta directors. Yet answer key has it going ortho…?</p>
<p>are you going about NMe? i dont see a CN…</p>
<p>but NMe is an op director</p>
<p>hey Batman, can you check your lecture 10 notes? is there anything that can reduce carboxylic acids? i wrote “None of these work for carboxylic acids” but i don’t know what i’m referring to</p>
