The specific rotation of text ! !α ! ! text -D- glucose is +113° and that of text ! !β ! ! text -D- glucose is +19° . The specific rotation of their mixture, in equilibrium, is +52° .

Q. The specific rotation of equilibrium mixture of $α -$ D-glucose and $β -$ D-glucose, is:

$+ 19^{\circ}$

$+ 112^{\circ}$

$+ 52^{\circ}$

$+ 100^{\circ}$

The specific rotation of $α -D-$ glucose is $+ 113^{\circ}$ and that of $β -D-$ glucose is $+ 19^{\circ}$ . The specific rotation of their mixture, in equilibrium, is $+ 52^{\circ}$ .
