Question

According to Baeyer's theory-
(a) Cyclohexane and cyclopentane have equal angle strain
(b) Cyclohexane has more angle strain than cyclopentane
(c) Cyclohexane has less angle strain than cyclopentane
(d) Cyclohexane is strainless​

Answer 1

Answer:

Cyclohexane has less angle strain than cyclopentane is correct

Answer 2

Answer:

A. Cyclopentane is a more stable molecule with a small amount of ring strain, while cyclohexane is able to adopt the perfect geometry of a cycloalkane in which all angles are the ideal 109.5° and no hydrogens are eclipsed; it has no ring strain at all.

B. This bond angle causes cyclopropane and cyclobutane to be less stable than molecules such as cyclohexane and cyclopentane, which have a much lower ring strain because the bond angle between the carbons is much closer to 109.5o. ... Transannular strain exists when there is steric repulsion between atoms.

D. All the three forms (chair form, boat form and twist boat form) of cyclohexane is/are free from angle strain. They are strainless conformations and maintain the normal sp3 tetrahedral bond angle of 109o. Hence, there is no angle strain.
