WebAssuming that the molecule is a hydrocarbon (meaning it is made of only carbon and hydrogen) then the number of hydrogens will depend on the number of bonds that carbon has to other carbons. Carbon wants to have 4 bonds. A double bond counts as 2 bonds. Take the following carbon chain as an example: CH3--CH==CH2 WebFigure 5.8.2: This molecules has a plane of symmetry (the vertical plane going through the red broken line perpendicular to the plane of the ring) and, therefore, is achiral, but has has two chiral centers. Thus, its is a meso compound. Other Examples of meso compounds teresa edwards ugaWebA molecule that contains two or more chiral centers may or may not be chiral. If a molecule containing two or more chiral centers has a plane of symmetry, it is achiral and is called a meso compound. When there is no plane of symmetry, the molecule is chiral.

WebCompounds that are optically inactive as they are achiral. Compounds that had the plane of symmetry is a special category called mesocompound. Which has chiral centre but the molecules itself are achiral. The 2^n is a general rule to estimate the number of stereoisomer, it won't help in the case of mesocompound. WebJul 30, 2024 · Chirality Test 1: Draw the mirror image of the molecule and see if the two molecules are the same or different. If they are different, then the molecule is chiral. If they are the same, then it is not chiral. (This is the most comprehensive test but is the most difficult to apply.)
