WebMost Stable Energy Confirmations Staggered, Low Energy Largest Substituents in Stable Energy Confirmations Separated By 180 Degrees Gauche Biggest substituents separated by 60 degrees relatively unstable, but more stable than eclipsed. Gauche Eclipsed Highest Energy Confirmation, Most Unstable Cyclic Alkane Formula CnH2n WebThe video was saying that according to the old theory of planar cycloalkane structures, cyclopentane would be assumed to be the most stable due to having the bond angles closest to the ideal 109.5 degrees, and therefore the lowest bond strain. WebJun 13, 2024 · In cyclopropanes the angles are 60. The lowest energy angle for the R2C=O system (SP2) is 120 degrees, in cyclopropanone it is 60. This is a very strained and unstable system, anything that reduces that strain is a positive change energywise.
