Which of the following is true of the α and β anomers of glucose?

Question

Quizplus · Accepted Answer

The α and β anomers of glucose differ in the position of the hydroxyl group (-OH) at the C1 carbon. In the α anomer, the -OH group at C1 is below the plane of the ring, while in the β anomer, it is above the plane of the ring. This difference in configuration causes them to rotate plane-polarized light to the right, but to different extents (+112° for α and +19° for β). Therefore, choice A is correct. Choice B is incorrect because the β anomer is, in fact, more stable due to a favorable interaction between the C1 hydroxyl group and the C5 hydroxyl group.
