Ph of cyclopentane
WebDec 15, 2010 · Published in Journal of Toxicology and Environmental Health, Part A: Current Issues (Vol. 58, No. 1-2, 1999) WebCyclopentane has very little angle strain (the angles of a pentagon are 108º), but its eclipsing strain would be large (about 10 kcal/mol) if it remained planar. Consequently, the five-membered ring adopts non-planar puckered conformations whenever possible. Rings larger than cyclopentane would have angle strain if they were planar.
