In … WebIn general, if you have a small molecule with no sp3 centers in the molecule, the molecule is planar. But there are many exceptions. Here are a few common ones: - Water is planar. The oxygen is sp3 but there are only 3 atoms so there's nothing to stick out of the HOH plane. - Allene is not planar. WebDavison et al. (2016) mapped the “chirality locus” to a 0.4 Mb region and determined that Lsdia2 is the likely candidate for determining dextral or sinistral coiling.

WebThe word chirality comes from the Greek (kheir), which means “hand,” a common chiral item. A chiral item or system is distinct from its mirror image; that is, it cannot be overlaid onto it. Golf clubs, scissors, shoes, and a corkscrew are examples of chiral objects that have a “handedness.”. As a result, right-handed and left-handed ...
