WebCyclopropane is a cycloalkane molecule with the molecular formula C 3 H 6, consisting of three carbon atoms linked to each other to form a ring, with each carbon atom bearing two hydrogen atoms. The bonds between the carbon atoms are a great deal weaker than in a typical carbon-carbon bond. This is the result of the 60° angle between the carbon … WebAug 13, 2024 · For cyclopropane and cyclobutane, the strain energy is about 110 kJ/mol. Cyclobutane can enter a "puckered" formation that slightly relieves some torsional strain. Cyclopentane, which is non-planar can remove some of the strain and has only about 25 kJ/mol of strain.
