Explanation of Solution
a) The given structure of
In,
L and D indicate the absolute configuration of a compound. If hydroxy group attached with chiral centre is to the right side and present on the bottom, then the carbohydrate is in D form but if hydroxy group is present to the left side then the carbohydrate is in L-form.
The name of the given compound is
b) The given compound is xylitol.
The alcohol derivative of xylose is xylitol in which the reduction of
c) The given compound is
Sugar molecule that has six-membered-ring is known as pyranose and sugar molecule that has five-membered-ring is called furanose.
The given compound is formed when
Thus, the structural formula of
d) The given compound is
L and D indicate the absolute configuration of a compound. If hydroxy group attached with chiral centre is to the right side and present on the bottom, then the carbohydrate is in D form but if hydroxy group is present to the left side then the carbohydrate is in L-form.
The given compound is formed when
Thus, the structural formula of
e) The given compound is
The given compound is formed when hydroxyl group is replaced by methoxy group as shown below.
Thus, the structure of
