WebSolution. Ethane will undergo substitution reaction. Usually one hydrogen atom will be replaced by one chlorine atom. (I use the word usually since more than one atom can be replaced, but less likely.) However, this reaction needs light, and it will not occur in the dark. First, Cl-Cl bond will be broken symmetrically. WebA chiral molecule is an enantiomer of its mirror image. As well, a chiral molecule and its mirror image are enantiomers. Diasteriomers have multiple stereocenters, each diasteriomer also often has an enantiomer. You're thinking of Meso compounds where a Diasteriomer isn't chiral since it doesn't have an enantiomer. Some Diasteriomers are indeed ... coach tony miller

WebThe rule of thumb is: chiral carbon centers are carbon atoms that are attached to four different substituents, that are placed at the corners of a tetrahedron. Chiral carbon atoms are also referred to as ‘stereogenic carbons’ or ‘asymmetrical carbon atoms’. WebIn most cases, the easiest way to decide whether a molecule is chiral or achiral is to look for one or more stereocenters - with a few rare exceptions, the general rule is that molecules with at least one stereocenter are chiral, and molecules with no stereocenters are achiral.
