A) mutor rotation
B) rotatory motion
C) inversion
D) specific rotation
Correct Answer: B
Solution :
The optical rotation of sugar (sucrose) is\[+\,66.5{}^\circ \]. On hydrolyzing with dilute acid, it gives glucose and fructose \[({{[\alpha ]}_{D}}=-92.3{}^\circ ).\] Thus, direction of \[({{[\alpha ]}_{D}}=+\,52.5{}^\circ )\] optical rotation changes.
