Question

Match the chemical substances in Column I with type of polymers/type of bonds in Column II.

$\begin{array}{cc}ColumnI& ColumnII\\ P.Cellulose& 1.Naturalpolymer\\ Q.Nylon-6,6& 2.Syntheticpolymer\\ R.Protein& 3.Amidelinkage\\ S.Sucrose& 4.Glycosidelinkage\end{array}$

• A. P-2,3, Q-4, R-1,2, S-1
• B. P-1,4, Q-2,3, R-1,3, S-4
• C. P-2,4, Q-3, R-2,4, S-1
• D. P-1, Q-2,4, R-3, S-2,3,4

Answer 1

The correct option is B

P-1,4, Q-2,3, R-1,3, S-4

P. (1) and (4) Cellulose is a natural polymer and has a $C_1–C_4\beta$ -glycosidic linkage.
Q. (2) and (3) Nylon–6, 6 is a synthetic polymer of hexamethylenediamine and adipic acid and has amide linkages.
R. (1) and (3) Proteins are natural polymers of $\alpha$ amino acids joined by amide linkages (peptide bonds).
S. (4) Sucrose is a disaccharide of $\alpha$-D glucose and $\beta$-D – fructose and has $\alpha ,\beta$–glycosidic linkage.
