Give the (hawarth projection) cyclic
structureof d-fructose?
a. identify if it is cyclic structure
ofd-fructose
b. number of carbons in the ring
c. draw the straight chain fisher projection of this molecule
d. classify this sugar as reducing agent or non-reducing. write
anequation for its reaction with tollens reagent
e. classify this sugar based on the number of carbons and thenature
of the anomeric carbon.

a) The cyclic structure of D-fructose is drawn in the attachment

b)The carbons in the ring are 4

c) The diagram is shown in the attachment

d)This can be classified as a reducing agent. This is because it contains aldehyde that are oxidized to carboxylic acid.

e) The D-fructose sugar has anomeric carbon which is an aldehyde or hemiacetal. In fructose, both anomeric carbons are in acetal functional groups

Explanation:

The explanations is attached.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
