Question

4. One of the most interesting aspects of Emil Fischer's endeavors in carbohydrate chemistry was his ability to predict whether a plane of symmetry would be present in an aldohexose after it was treated with the appropriate oxidizing or reducing agent 4.1. Look at the aldohexose below. Is it optically active or not (does it possess a plane of symmetry?) CH-OH Give two reactions to convert this aldohexose into optically inactive products. Identify a different aldohexose, which would show similar characteristics

Explanation / Answer

4.1 There is no plane of symmetry in given d-galactose molecule . The absence , indicates the molecule may be optically active .
