Question
For the compound below, the number of 1 degree, 2 degree and 3 degree hydrogens, respectively is_____ A) 1, 6 and 0 B) 1, 3, and 1 C) 3, 6 and 2 Glucose has a specific rotation of +52.8 degree. Predict the concentration of a glucose aqueous contained in a 10 cm long polarimetry tube if a rotation of +15.8 degree was observed. A) 0.299 g/mL B). 334g/mL C) .0299 g/mL The stereochemical configuration of D-Threonine is (2R, 3S). Which of the following structural corresponds to the correct configuration?Explanation / Answer
Ans 1: option B is the correct alternative as there are 1 primary, 3 Secondary, 1 tertiary Hydrogen in the compound.
Ans 2 : The correct ans if the 3 option 0.0299 g/mL . According to the equation used in poraimeter.
a (given) = a ( obs ) / length * concentration
Where a = specific rotation in degree.
Ans 3 Incomplete question.
