Question

How it is used to explain
the reactivity of cyclopropane and cyclobutane rings ?​

Answer 1

Answer:

Because cyclopropane and cyclobutane are small, rigid molecules, they possess high reactivity due to their inherent strain, because the orbitals involved in bonding are forced to deviate from the ideal sp3 tetrahedral angle of 109.5°.
