The first-order rate plot of the intensity of the ECD spectra at a given time interval gave the rate of racemization. Mild racemization was observed in polar solvents, whereas a relatively fast rate was obtained in less polar solvents. In addition, the TTF groups of the allene also accelerate the racemization rate. peter grill and the philosopher\\u0027s uncensoredWebMay 30, 2024 · Well, the left half of allene is perpendicular to the right half. In order for a molecule to be planar, the whole molecule has to be planar. A simplified explanation is that the central carbon atom's px and py orbitals are aligned to make perpendicular π bonds, corresponding to perpendicular CH2 groups. starlight movie theater charlotte nc
