Question

Which of the following is optically active?
1) Formic Acid 2) Propionic Acid 3) Succinic Acid
4) Lactic Acid 5) Meso-tartaric Acid

Answer 1

meso tartaric acid
is a optically active compound

Answer 2

Lactic Acid is optically active

Explanation:

1. Formic Acid- It is an optically transparent material.It has reasonable electrolyte because it facilitates proton transport.
2. Propionic Acid-It has no carbon atom in propanoic acid is seen to be bonded to four different atoms or groups of atoms. It is optically inactive in nature.
3. Succinic Acid- It is optically inactive .Succinic acid is an alpha,omega- dicarboxylic acid.
4. Lactic Acid-It has chiral molecule because it has a chiral carbon atom or asymmetric carbon,then it is optically active.
5. Meso-tartaric Acid-It is optically inactive due to the presence of molecular symmetry.

Option (4) Lactic acid is correct.
