| Q. |
The polymer obtained by the condensation of hexamethylene diamine and adipic acid is – |
| A. | Nylon 66 |
| B. | Terylene |
| C. | Tollen's |
| D. | Bakelite |
| Answer» A. Nylon 66 | |
|
Explanation: Polymers are very high molecular mass substances each molecule of which consists of very large number of simple structural units joined together though covalent bonds in a regular fashion. Polymers whose repeating structural unit are derived from two or more types of monomer units are called copolymers. For examples, in case of nylon 66, the repeating structural unit is derived from two monomer units - hexamethylenediamine and adipic acid. |
