Match List I with List II
Choose the correct answer from the options given below: |
A-II, B-IV, C-I, D-III A-III, B-II, C-IV, D-I A-I, B-II, C-III, D-IV A-IV, B-II, C-III, D-I |
A-II, B-IV, C-I, D-III |
The correct answer is option 1. A-II, B-IV, C-I, D-III. Let us look at the different molecules and their bonding: A. Terylene: Terylene is a type of polyester, which is a polymer composed of repeating units linked together by ester linkages. These ester linkages \((-COO-)\) are formed between the carboxyl (-COOH) groups of one monomer and the hydroxyl \((-OH)\) groups of another monomer during the polymerization process. B. Nylon: Nylon is a synthetic polymer known as a polyamide, which is formed by the condensation polymerization of monomers containing both carboxyl \((-COOH)\) and amino \((-NH_2)\) groups. The amide linkages \((-CONH-)\) are formed between the carboxyl group of one monomer and the amino group of another monomer C. Cellulose: Cellulose is a polysaccharide found in the cell walls of plants and is composed of repeating glucose monomers linked together by glycosidic linkages \((-C-O-C-)\). These linkages are formed between the anomeric carbon atom of one glucose molecule and the hydroxyl group of another glucose molecule during polymerization. D. RNA: RNA (ribonucleic acid) is a nucleic acid composed of nucleotide monomers. The backbone of RNA is formed by phosphodiester linkages \((-PO_2-)\) between the 3' carbon of one nucleotide and the 5' carbon of the next nucleotide in the chain. A-II (Terylene contains ester linkages), B-IV (Nylon contains amide linkages), C-I (Cellulose contains glycosidic linkages), D-III (RNA contains phosphodiester linkages). |
