Which is more stable and why ? A. Cyclopentane B. Cyclohexane C. Cycloheptane
Dear Vikalp Agrawal
Cyclohexane is most stable than cyclopentane because in cyclopentane the ring strain is 6 kcal/mol while in cyclohexane the ring strain is 0 kcal/mol. Cyclopentane have two conformation twist and envelop. In both of them the C-C bonds are eclipse to each other and feel strain. In contrast to this, cyclohexane chair form is most stable because all C-C bonds are staggered to each other and do not experience torsional strain.
Hence cyclohexane is more stable than cyclopentane.
