Please help I have no idea how to start and there no answer key I genuinely suck at freaking Newman projection and this class has been the bane of my existence. First off I think I would be lowest and h would be the highest but other than that I have no idea online is not help either bc chem warrior help me out

Can someone pls help me step by step on how to do this I have no answer key so genuinely have no idea if what I’m doing is right. I would believe I is the lowest energy bc of the fact there is gauche as well between the other priority groups but online it tells me it is b and the highest energy conformation I would assume is H bc the bulkier groups are nearby otherwise im confuse for the rest. I would assume A is an diasteormer bc some of the dashes and wedges change in one carbon but the other carbon stayed the same and yea like idk pls pls pls help im stressed

Hi everyone,

I’m taking CHEM 237 with Samantha Robinson and I’m trying to figure out the best way to prepare for the cumulative final.

• Do every old exam from start to finish
• Focus on the most recent exams
• Review lecture slides and then do practice exams
• Spend more time on worksheets instead

For people who have taken Robinson before, how similar was the final to the practice exams and previous midterms? Did you find that repeatedly doing old exams was the best use of your time or the worksheet, or was there something else that helped more?

I’m in Robinson’s class right now and starting to study for the final, but I honestly feel overwhelmed with all the material. For people who have taken her class before (or are in it now), what helped you the most?

Did you focus more on:

• lecture notes
• homework problems
• practice exams
• textbook problems
• conceptual understanding vs memorization

Also, how similar was the final to the midterms? Were there any topics you wish you spent more time on?

Trying to study efficiently, so any advice or study strategies would really help. Thanks!
