Answer 1

Answer:

Molecules that posses chirality are optically active. Chiral carbon is the one having all different groups attached.

Propanoic acid is: CH

3

CH

2

COOH has no chirality thus its optically inactive

Glyceraldehyde:HOCCH(OH)CH

2

OH has a ciral center thus its optically active

Lactic acid is H

3

CCH(OH)COOH has a chiral center thus its optically active

Glucose is HOCCH(OH)CH(OH)CH(OH)CH(OH)CH

2

OH has multiple chiral center thus its optically active
