The first 12 chapters of the textbook Organic Chemistry: A Tenth Edition are now freely accessible to students through OpenStax, an educational initiative of Rice University. On Sept. 20, students and faculty will have free access online to the full version of this historically costly textbook that is a required material for organic chemistry courses nationwide. OpenStax is also providing free, aligned supplemental resources, including lecture slides, test items and a solution manual on their website. For those preferring print materials, the textbook will be available to purchase at an affordable price in hardcover and paperback.
