RefineYour organic chemistry textbook, remembered
Organic chemistry isn't a list of reactions to memorize. It's knowing why a substrate goes SN1 or SN2, and why a nucleophile attacks where it does. Cards with reaction names on them don't build that.
The kind of question you get
A tertiary substrate ___ an SN2 reaction.
- blocks (right)
- speeds up
- has no effect on
Why: three groups crowd the carbon, so the nucleophile can't attack from behind. The stable tertiary carbocation favors SN1 instead.
How it works
- Scan the pages you're assigned, or import your textbook's PDF. Using a free OpenStax textbook? Download its PDF and import it.
- Every chapter becomes something you can finish: a short read of what matters, and the full read when you need it. In a PDF, equations stay equations.
- A concept map of how the chapter's ideas affect each other.
- Questions about how it works, written from each chapter, with wrong answers that are wrong for a reason.
- A few minutes a day. Each question comes back just before you'd forget it, so the chapter is still there on exam day.
- Listen on the way to class, with each line lit as it's read.
What it is not
Refine helps you remember your textbook. It doesn't replace lectures or working the problems, and it won't do your homework.
