Cyclopentane and cyclohexane

WebCyclopropane (C3H6) is the smallest cycloalkane, whereas cyclohexane (C6H12) is the most studied, best understood, and most important. It is customary to represent cycloalkane rings as polygons, with the understanding that each corner corresponds to a ... whereas cyclopentane and higher cycloalkanes are virtually free of angle strain. WebDec 21, 2014 · Cyclopentane can relieve most of the torsional strain by puckering, but this increases ring strain. Cyclohexane can pucker into a chair form to relieve both torsional and ring strain. But larger rings such as cyclooctane can also pucker to relieve torsional and ring strain. Answer link
