Could someone please explain the concept of "shepherd's lema" in a clear way? Also, could you provide an example to further illustrate what it is? Also, please write legibly. I don't mean to be rude, but part of the reason why I'm asking this is the last person who answered my question did so through handwriting I couldn't clearly read, so I didn't actually understand the answer. If you write down the answer please be sure your writing is very...

Without asking, how could you tell whether you were talking to astronauts on the Moon or on Mars? Also, a huge sidenote, this question comes directly from the book and the explaination is not in the app, could someone please take a look at it and fix it? )): There’s already multiple instances where questions are skipped )): & I don’t how to report the problem )): thank you in advance !!(:
Could someone please identify the steps I have to follow when determining a chemical structure based on Molecular formula, IR spectrum , HNMR, 13CNMR. I know what each test identify in a structure I just do not understand how to prioterise which one you should look at first and how could this help in the next step. Thank you
