Answer #1

D- Tartaric acid makesw racemic acid. This is also called levo tartaric acid.

It rotates counter clock wise.

We can synthesize the spectroscoipic methods along with scaterring experiments.

There we can observe specific optical rotation at nearly 0.32mM.

The less natural form of tartaric acid (D-tartaric) has a specific optical rotation of -12o

The mesomeric form is synthesized not occured naturally.

It occurs from fermentation of Glucose.

It occurs naturally. It is used as anti oxidants in foods.

It is treated with lime to form calcium tartate.

For the purification of tartaric acid the specific rotation decreases.

It is used mostly in beverages.

The synthetic form of tartaric acid is optically inactive (its specific rotation is 0). However, its melting point is significantly different from that of meso-tartaric acid, which is also optically inactive. Based on this observations deduce the structure(s) of component(s) of the synthetic form of tartaric acid.
