WebAug 27, 2024 · Cyclobutane is a four membered ring. In two dimensions, it is a square, with 90 degree angles at each corner. However, in three dimensions, cyclobutane is flexible enough to buckle into a "butterfly" shape, relieving torsional strain a little bit. When it does that, the bond angles get a little worse, going from 90 degrees to 88 degrees. easy patio shade ideas
