| Section2 = | Section8 = }} Cyclobutane, C4H8, with a molecular mass of 56.107g/mol,'s a four carbon alkane in which all the carbon atoms are arranged cyclically, hence cyclobutane. Cyclobutane's a gas and commercially available as a liquefied gas. Cyclobutanes are cyclobutane derivatives. Conformation The 90 degree bond angles between carbon atoms are significantly strained and as such have greater bond energies than either linear butane molecules or larger homocyclic alkanes such as cyclohex… (More on Cyclobutane)
