Match the polymers given in Column I with the type of linkage present in them given in Column II.



(i) Terylene – (b) Ester linkage


We know, terylene is a polyester, and a polyester is a polymer having the ester linkage.



(ii) Nylon – (d) Amide linkage


Nylons are polyamides which means they have an amide linkage.




(iii) Cellulose – (a) Glycosidic linkage


Explanantion:


Cellulose is derived from D glucose units which have the β ( glycosidic bonds. The linkage here observed is termed as glycosidic linkage.



(iv) Protein – (d) Amide linkage.


If we look at the structure of protein we will find the presence of amide linkage along with amino acids and polypeptide chain.


(v) RNA – (c) Phosphodiester linkage


A phospodiester bond is a covalent bond in which a phosphate group joins adjacent carbons through ester linkages.


The phosphodiester bond links a 3' carbon to a 5' carbon in DNA and RNA.
