Is a meso compound and enantiomer?

Meso compounds and enantiomers are organic compounds containing stereocenters. They are different from each other in many aspects. The main difference between meso compound and enantiomers is that meso compounds have an identical mirror image whereas enantiomers have a non-superimposable mirror image.

What are Mesomers?

Mesomers are the type of organic compounds in which two chiral carbons are present and those two are similar. The net rotation of plane polarised light due to this reason is zero for these compounds. Example: 2,4 pentane diol.

What defines a meso compound?

Meso compounds are achiral compounds that has multiple chiral centers. It is superimposed on its mirror image and is optically inactive despite its stereocenters.

Why is meso not chiral?

Explanation: A meso compound is a molecule that contains two stereogenic centres with a plane of symmetry. A meso compound is not a chiral molecule because it is superimposable to its mirror image. Enantiomers by definition are one chiral molecule and its mirror image.

Which of the following is meso compound?

Given compound, pentane-2,4-diol is meso due to the presence of plane of symmetry.

How do you know if your sugar is D or L?

From its structure, if the –OH group attached to the bottom-most asymmetric center (the carbon that is second from the bottom) is on the right, then, the compound is a D- sugar. If the –OH group is on the left, then, the compound is a L-sugar.

What is difference between D D and L L?

Summary – L vs D Isomers The main difference between L and D isomers is in the position of –OH group in the penultimate carbon atom. In D isomer, the OH- group of the penultimate carbon is positioned on the right side whereas, in L isomer, the OH- group of the penultimate carbon is positioned on the left side.

What is meso isomerism?

A meso compound or meso isomer is a non-optically active member of a set of stereoisomers, at least two of which are optically active. This means that despite containing two or more stereogenic centers, the molecule is not chiral.
