Question

Which of the following is most stable cycloalkane? (A)cyclohexane (B)cycloheptane (C)cyclopropane (D)cyclopentane

Answer 1

Answer:

(a) Cyclohexane

Explanation:

Cyclohexane exists in many conformational structures, like the chair form, half chair form, boat form, etc. Baeyer's Angle Strain Theory explains the stability of cycloalkanes. Stable cycloalkanes cannot be formed with carbon chains of just any length. Recall that in alkanes, carbon adopts the sp³ tetrahedral geometry in which the angles between bonds are 109.5°. For some cycloalkanes to form, the angle between bonds must deviate from this ideal angle, an effect known as angle strain.
