I was reading this question, chemistry.stackexchange.com/questions/27095/… , can anyone explain how is numbering done in 1,6,7-trimethylnaphthalene? I have wracked my brain, but can't seem to figure out how 1,6,7 are assigned to the methyl groups.
Would someone redirect me to good practices for editing posts? I spent time trying to help with improving some entries, but I believe I could learn a thing or three. I am still wrapping my head around the Chemistry SE site, so please bear with me as I get up to speed.
I came across a post on the main site just now that I think could use some changes. I found the editing help page in the Help Center, but its write-up is pretty cursory and high-level.

If you click on your reputation tab it will display any losses due to downvotes etc. However it could also simply just have been somebody retracting an upvote (for whatever reason) which won't show up, I think.
Indeed. Not sure I can see down votes of specific edits. Perhaps some posts have been closed, leading to a decrease in my reputation. If so, these updates aren't well explained.
@FadedGiant Oh, now I get it. Can you also explain what is the rule that says that number 1 has to be given to that methyl which is at benzylic position. I mean, we could also give number "1" to the methyl group which is currently numbered 6, so it would become 1,2,5 trimethylnaphthalene.
I understand that the endo product is, at least in all cases in my textbook, the major product in a Diels-Alder reaction. However, I don't understand why this is the case.
The explanation in my textbook says that the endo product allows for more interaction between the diene and dienophile duri...
Q1. Is the $\sigma_\ce{C-H}$ bond a donor in this reaction? If not, then can we take the alternate combination (HOMO of alkene, LUMO of the $\ce{C-H}$ bond and, HOMO of the carbonyl)?
Q2. We can also draw the LUMO of the carbonyl group in the other possible manner(simply flip the shaded lobe on e...
In a science exhibition in 2011 , I and my friend made a volcano that used vinegar and baking soda for the 'effects'. There was another group that made volcano too and they had brought their own supplies. But before the exhibition started, the members of other group came to us and asked us if we...
