aj and u DJR anda (C)adnas Specific rotations of freshly prepared aqueous solutions of l and II are +112 and +18.7 respectively. On standing the optical rotation of aqueous solution of 1 slowly decreases to give a final value of +52.7 due to equilibrium with I1. Under this state of equilibrium,what is the ratio H:1? (a) 0.57 (d) 5.9 (c) 1.75 (b) 1.00
