Question

The most strained cycloalkane is
a)Cyclopropane
b)Cyclobutane
c)Cyclopentane
d)Cyclohexane

Answer 1

Cyclopropane is one of the cycloalkanes that has an incredibly high and unfavorable energy, followed by cyclobutane as the next strained cycloalkane. Any ring that is small (with three to four carbons) has a significant amount of ring strain; cyclopropane and cyclobutane are in the category of small rings.

So option A is correct
