What is the specific rotation value of a sucrose solution?

Best Answers

Sucrose rotates the polarized light to the right, and is called a right-hand sugar (dextrorotatory). The direction of rotation is indicated by a plus (+) for dextrorotatory sugars. read more

In chemistry, specific rotation ([α]) is a property of a chiral chemical compound.: 244 It is defined as the change in orientation of monochromatic plane-polarized light, per unit distance–concentration product, as the light passes through a sample of a compound in solution. read more

enatiomeric excess (ee) may be calculated using the observed rotation (α obs) compared to the specific rotation [α]. e.e. = |R-S| / (R+L) * 100%= |α obs|/|[α]| * 100% The e.e. divided by 100 and multiplied by the absolute value of the specific rotation of the pure compound will result in the absolute value of the observed rotation by the mixture. read more
