  • • Key concept: Markovnikov's rule and its regiochemical basis.
  • • Definition: Degree of unsaturation = (2C+2+N−H−X)/2.
  • • Worked example: HBr addition to 2-methyl-2-butene, step by step.

FAQ

Can I combine multiple lectures into one guide?+

Yes. Paste up to 5 sources on the free tier (25 on Pro) and Readlis merges them into a single deduplicated guide organized by topic, not by source.

How long is a typical study guide?+

A 60-minute lecture produces a 4–6 page guide. A full textbook chapter produces 8–12 pages. Guides scale with source density, not word count.

Are the practice questions solved?+

Yes. Every practice question ships with a full worked solution, hidden by default so you can attempt it first.

Can I export to Notion or Google Docs?+

Yes — Markdown copy-paste works cleanly in Notion, Google Docs, Obsidian, and Craft. PDF export is one click.

Do I need to sign up?+

No. Generate a guide without an account. Sign up (free) to save, edit, and re-export guides later.
