Answer 2

Answer:

Optical activity of lactic acid. ... When a plane polarized light is passed through a lactic acid solution the plane of polarized light gas rotated through a certain angle. This property of rotating the phane of polarized light towards right (clockwise) or towards (left)(anticlockwise) is called optical activity

Explanation:

Optical activity of lactice acid. In lactic acid molecule there is an asymmetric chiral carbon atom with four different groups which lead to two spatial configurations (d-lactic acid l-lactic acid) which are super imposable mirror images of each other.

d-lactic acid rotates the plane of polarized light towards right whereas l-lactic acid rotates the plane of polarized light towards left, which can be detected by polarimeter. In above structure (I) is representing the (+)(+) isomeric form or dextro rotatory form of lactic acid, while structure (II) is representing (-)(−) isomeric form or laevo rotatory for of lactic acid.
