All Chapters Video 1.7 Cycloalkanes and Ring Strain Chapter OutlineChapter Quiz Question? Ask Dr. Mike! Lesson Summary Cycloalkanes are alkanes that are cyclic –in other words, ringed alkanes or alkanes with rings in them. Cyclohexane is the most stable cycloalkane. How to draw chair conformations of cyclohexane (follow along!): Axial vs. Equatorial: Note: Equatorial positions are more stable (lower energy) than axial for larger groups because of 1,3-diaxial interactions. Placing the largest substituents in the equatorial positions will usually achieve the greatest stability in cyclohexane rings. Trans vs. Cis cyclohexanes Cis – two substituents going in same directionTrans – two substituents going in opposite direction Lesson 1.7 Cycloalkanes and Ring Strain 1.0 Meet Dr. Mike Christiansen! 1.1 Molecular Bonding Geometry and Hybridization 1.1 Quiz Video Solution 1.2 Condensed Formulas and Line-Bond Formulas 1.2 Quiz Video Solution 1.3 Sigma and Pi Bonds 1.3 Quiz Video Solution 1.4 Orbital Hybridization 1.4 Quiz Video Solution 1.5 Resonance Structures 1.5 Quiz Video Solution 1.6 Newman Projections 1.6 Quiz Video Solution 1.7 Cycloalkanes and Ring Strain 1.7 Quiz Video Solution Instructor Dr. Mike Christiansen Dr. Christiansen is a chemistry professor at Utah State University and has a PhD in organic chemistry.
