Two form of D–Glucopyranose are –D(+)–Glucopyranose and –D(+)–Glucopyranose. These are anomers
(a pair of stereoisomers which differ in configuration only around C1 are called anomers).
5.(B)
PMMA is used in bullet proof glass.
6.(A)
Refer NCERT, Class XII-Part-II, Page-436
7.(BC) Sugar X is non reducing because it is in acetal form and its glycosidic linkage is -glycosidic linkage.
Sugar Y is reducing because it is in hemi acetal form and its glycosidic link is -glycosidic linkage.
8.(A)
Cellulose is a polymer of -D-(+)-glucopyranose.s
9.(A)
It is present in the cell wall of plant.
10.(A) Biodegradable polymers contain functional groups similar to the functional groups present in
biopolymers. Aliphatic esters and some polyamides are biodegradable. These polymers have high surface
area and minimal chain branching.
11.(A) 18 ATPs are involved in the formation of one glucose molecule as shown in the reaction below :
6 CO2  12 NADPH  18 ATP  C 6H12O6  12 NADP  18 ADP
12.(A) Dacron is a polyester and polyesters are condensation polymers.
13.(A) Quinoline is an alkaloid, it is not present in DNA, DNA has four nitrogen bases adenine, guanine,
cytosine and thymine.
