Cyclohexanes: Crash Course Organic Chemistry #7

Teacher or professor: CrashCourse
Subject: History, Computer Science, Engineering, Statistics, Sociology, Theater
Content of the Lesson: Hexagons appear all over the natural world from honeycomb to bubbles, and they even appear in organic chemistry! In this episode of Crash Course Organic Chemistry, we're learning all about cyclohexanes, including how rings pucker to relieve strain, the boat and chair conformations, and how ring flips can switch substituents from axial to equatorial. We'll practice a lot of chair flips, but don't flip an actual chair just yet! Lots of practice is key to understanding organic chemistry's favorite manifestation of the hexagon.
