(a)
Interpretation:
Given sugar below is a D- or L- sugar has to be determined.
Concept Introduction:
Chiral compounds are optically active and they rotate the plane polarized light. Some compounds rotate the plane polarized light clockwise and some rotate it anticlockwise. Compounds that rotate clockwise are known as dextrorotatory and those which rotate anticlockwise are known as levorotatory. Dextrorotatory compounds are indicated with a “(+)” sign while levorotatory compounds are indicated with a “(-)” sign. In case of sugar, the chiral carbon that contains hydroxyl group farthest from the most oxidized end of the molecule is considered. If the hydroxyl group is present on the right side, then the isomer is said to have D-configuration and if it is present on the left side, then the isomer is said to be in L-configuration.
(b)
Interpretation:
Given sugar below is a D- or L- sugar has to be determined.

Refer part (a).
(c)
Interpretation:
Given sugar below is a D- or L- sugar has to be determined.

- Show the mechanism steps to obtain the lowerenergy intermediate: *see imagearrow_forwardSoap is made by the previous reaction *see image. The main difference between one soap and another soap isthe length (number of carbons) of the carboxylic acid. However, if a soap irritates your skin, they mostlikely used too much lye.Detergents have the same chemical structure as soaps except for the functional group. Detergentshave sulfate (R-SO4H) and phosphate (R-PO4H2) functional groups. Draw the above carboxylic acidcarbon chain but as the two variants of detergents. *see imagearrow_forwardWhat are the reactions or reagents used? *see imagearrow_forward
