Interpretation Introduction
Interpretation: In Haworth projection, the direction of any
Concept introduction: The structural representation of sugar molecule in cyclic form is known as Haworth projection. The substituents which are present on the right side in the Fischer projection are drawn below the ring in the Haworth projection. Similarly, the substituents which are present on the left side in the Fischer projection are drawn above the ring in the Haworth projection.

4. A sample containing ethanol and water was found to have n6 = 1.3400. Calculate the
exact percentage of ethanol and water in this example. Show your work. (Hint: Solve
this mathematically. Assume a linear relationship between concentration and refractive
index. You can make the y-intercept the refractive index of water, and use the slope
formula to find the slope. The x axis (concentration) will be from 0% ethanol to 100%
ethanol. From this information, you can get the equation of the line, then plug in your
numbers from there.)
Gentiobiose has the molecular formula C12H22O11 and has been isolated from gentian root and by hydrolysis of amygdalin. Gentiobiose exists in two different forms, one melting at 86°C and the other at 190°C. The lower melting form is dextrorotatory ([α] 16°), the higher melting one is levorotatory ([α] -6°). The rotation of an aqueous solution of either form, however, gradually changes until a final value of [α] 9.6° is observed. Hydrolysis of gentiobiose is efficiently catalyzed by emulsin and produces two moles of D-glucose per mole of gentiobiose. Gentiobiose forms an octamethylether, which on hydrolysis in dilute acid yields 2,3,4,6-tetra-O-methyl-D-glucose and 2,3,4-tri-O-methyl-D-glucose. What is the structure of gentiobiose? EXPLAIN IN DETAIL.
