steric strain

Can Bicyclic Be Strained? Ring strain can be considerably higher in bicyclic systems. For example, bicyclobutane, C4H6, is noted for being one of the most strained compounds that is isolatable on a large scale; its strain energy is estimated at 63.9 kcal mol− 1 (267 kJ mol− 1). Does cyclohexane have ring strain? Cyclopentane is
