In physics, chirality may be found in the spin of a particle, where the handedness of the object is determined by the direction in which the particle spins. Not to be confused with helicity, which is the projection of the spin along the linear momentum of a subatomic particle, chirality is an intrinsic quantum mechanical property, like spin. Although both chirality and helicity can have left-handed or right-handed properties, only in the massless case are they identical. In particular for … WebThe understanding of chirality transmission between the alcohol and the triarylsilyl group can be extrapolated to explain the importance of the phenyl groups in silylation-based kinetic resolutions.
