WebAug 28, 2013 · C-C-C bond angle in rings should be approximately 109.5° degrees which in case of small rings like cyclopropane, bond angles are 60° whereas tetrahedral 109.5° bond angles are expected. The intense angle strain leads to nonlinear orbital overlap of its sp3 orbitals. Because of the bond's instability, cyclopropane is more reactive than other ... WebThe angles between electron domains are determined primarily by the electronic geometry (e.g., 109.5° for a steric number of 4, which implies that the electronic shape is a tetrahedron) These angles are adjusted by the hierarchy of repulsions: (lone pair - lone pair) > (lone pair - bond) > (bond - bond) Found this somewhere.Hope this helps:) how does nuvaring release hormonesWebCyclopentane is a 5-membered cyclic ring; bond angle is 108o which is only 1o off from what a normal C-C-C bond angle wants to be; cyclopentane is stable molecule, unlike cyclopropane and cyclobutane.
