JEE Advanced2025ChemistryBiomoleculesActual
A linear octasaccharide (molar mass =1024 ~g ~mol ⁻¹ ) on complete hydrolysis produces three monosaccharides: ribose, 2-deoxyribose and glucose. The amount of 2-deoxyribose formed is 58.26 %( w / w ) of the total amount of the monosaccharides produced in the hydrolyzed products. The number of ribose unit(s) present in one molecule of octasaccharide is Use : Molar mass ( . in . g mol ⁻¹ ) : ribose =150,2 -deoxyribose

Step-by-step solution
M . M .=1024 Octasaccharide + M . M .=126 7 H ₂ O aligned & Ribose + 2deoxyribose + glucose & Total mass =1024+126=1150 aligned aligned & 58.26= 134 n 1150 100 & 66.999 100 =134 n n=4.99=5 aligned 5 units of 2-Deoxyribose 1150=(5 150)+( x 150)+( y 180) aligned & 1150= 750 _ 5 unit + 150 x ₃₀₀+ 180 y ₁₈₀ & 2 unit 1 unit aligned n = 2.00
