1.

Answer» Correct choice is (c) 64 Explanation: When either α or β FORMS of glucose are dissolved in water and are allowed to stand, an EQUILIBRIUM MIXTURE of both forms is formed (36% α-form and 64% β-form). This is due to a spontaneous change in SPECIFIC rotation of an optically active COMPOUND with time to an equilibrium value. This phenomenon is called as mutarotation.
