Cyclobutane butterfly conformation
Did you know?
WebCyclobutane has an overall strain of 110 kJ/mol. Cyclopentane also adopts a non-planar conformation known as envelope conformation. Compared to the hypothetical planar form of cyclopentane, the envelope form has its bond angles slightly reduced, which marginally increases the angle strain. WebThe cyclobutane molecule will seek to reduce both stresses, and to achieve this it adopts what is known as the butterfly or puckered (in English, puckered) conformation. …
