Planar chirality, also known as 2D chirality, is the special case of chirality for two dimensions. Most fundamentally, planar chirality is a mathematical term, finding use in chemistry, physics and related physical sciences, for example, in astronomy, optics and metamaterials. Recent occurrences in latter two fields are … See more This term is used in chemistry contexts, e.g., for a chiral molecule lacking an asymmetric carbon atom, but possessing two non-coplanar rings that are each dissymmetric and which cannot easily rotate about the See more Chiral diffraction Papakostas et al. observed in 2003 that planar chirality affects the polarization of light diffracted by … See more • Metamaterial • Chirality (electromagnetism) See more WebDec 17, 2024 · You need to be able to quickly spot chiral centers in molecules. All straight-chain alkyl group carbons (CH 3 or CH 2 units) will not be chiral centers because these groups have two or more identical groups (the hydrogens) attached to the carbons. Neither will carbons on double or triple bonds be chiral centers because they can't have bonds …
