Make3 a model of cyclopentane. Does this molecule seem to have any ring strain in the sense that the three and four-membred rings do? The molecule is not completely strin-free because there is some eclipsing. Identify the eclipsed atoms or groups when the molecule is planar. In fact the molecule is not planar, but is puckered in either of two ways; (i) One C-atom is abover or below the plane defined by the other four coplanar C-atoms defining an envelope...
