A lab technician making a fresh sugar solution noticed that the optical activity of the sugar solution changed after the solution had been standing for several hours. This change in optical activity is best explained by the phenomenon called:
|A|| Tyndall effect|
|B|| Brownian movement|
|C|| Optical anomaly|
Ans. D The synthesis of sugar probably resulted in mostly one form of the sugar. According to the question, there was a change in optical activity. This is due to a phenomenon called mutarotation. The sugar solution that was made mutarotated to form its corresponding anomer, which changed the observed optical activity. The mutarotation will continue until an equilibrium is established.
