Propyl group - Wikipedia
In organic chemistry, propyl is a three-carbon alkyl substituent with chemical formula −CH2CH2CH3 for the linear form. This substituent form is obtained by removing one hydrogen atom attached to the terminal carbon of propane. A propyl substituent is often represented in organic chemistry with the symbol Pr (not to be confused with the element praseodymium). WebThe hyperconjugation of cyclopropyl groups with electron withdrawing π substituents such as C O is also possible and again the σ–π* interaction is very effective in the bisected conformation 106 (Fig. 3.51).The electron donation from the Walsh-type cyclopropyl σ orbital to the antibonding π* C O causes a decrease in the bond order of carbonyl group … list of scriptable objects unity

WebMay 20, 2016 · When you have a ring that has $4n$ π electrons it's anti-aromatic if you force it into a fully conjugated cycle.. Often such rings find a way to break the unfavorable (or at least, less favored) anti-aromatic conjugation. Large ones like cyclooctatetraene are likely to bend so all ring atoms are no longer in the same plane.
