What is the structure of meso tartaric acid?

What is the structure of meso tartaric acid?

Mesotartaric acid

Is tartaric acid a meso?

Tartaric acid also has a diastereomer called meso-tartaric acid. This molecule does have a plane of symmetry, and is therefore achiral. In general, any compound like this, having stereogenic carbons but also a plane of symmetry, is called a meso compound.

Why meso tartaric acid is optically inactive?

Meso tartaric acid is optically inactive due to the presence of molecular symmetry. It is optically inactive due to internal compensation i.e. the effect of one-half of the molecule is neutralized by other.

What is a meso compound?

What is Meso Compound? An achiral compound with chiral centres is known as a meso compound. Although it has two or more stereocenters, a meso compound has an internal plane of symmetry that makes it superimposable on its mirror image and is optically inactive.

What is the relation between meso tartaric acid and D tartaric acid?

Given meso tartaric acid and d-tartaric acid structural formula are respectively, From the above structural formula, the carbon −2 and carbon −3 are not mirror images of each other and the stereocenters are not identical. So, these are called diastereomers. The correct option is D.

What is the difference between D tartaric acid and L tartaric acid?

The difference in these forms is that they have an OH group on the right hand side in d- configuration, while on the left hand side in l- configuration. The structures are, they are (R) l- configuration and (S)d- configuration respectively.

Why tartaric acid is optically active?

Four forms of tartaric acid are known, of which two are optically active and two are optically inactive. The two optically active forms are mirror images of each other but not superimposable, that is, they are Enantiomers. (-)-Tartaric Acid: Rotate the PPL to the left (anti-clockwise) and is levorotatory.

Which structure is a meso compound?

In the simplest case, a compound with two chirality centers where there is the same set of four groups at each chirality center, the combination where the four groups are arranged such that the centers are mirror images of each other (i.e. where the molecule has an internal mirror plane) is a meso compound.

Which of the following is diastereomer of meso tartaric acid?

cis−trans isomers are always diastereomers. Given meso tartaric acid and d-tartaric acid structural formula are respectively, From the above structural formula, the carbon −2 and carbon −3 are not mirror images of each other and the stereocenters are not identical. So, these are called diastereomers.
