The monomeric repeating unit of Nylon-6 polymer is N H (C H 2 ) 5 C O which is derived from caprolactam. a. polyethylene b. polyvinyl chloride c. Teflon d. polypropylene e. polystyrene. How are polymers classified on the basis of structure? Draw the structure of the monomer and the basic repeating unit for each of the following polymeric substances. The numbers preceding the poly prefix designate the first and last carbon atoms of the backbone repeating unit. Determine the molar mass of Fraction 1 of Teflon, given avg repeat units and mol of polymer? Polytetrafluoroethylene (Teflon) has a repeat unit with the formula F 2 C—CF 2. Teflon is used for non-stick coating of pans and other cookwares . check_circle. For polyethylene, arguably the simplest polymer, this is demonstrated by the following equation. It likes its own company, but it doesn't like other molecules all that much. In the other approach, a compound that contains an amine at one end and acid at the other are polymerized to produce a chain with repeating units of (-NH-[CH 2]n-CO-)x. i. deduce monomers of a given polymer ii. 02) Complete the table given. The repeating unit or monomer of teflon is CF = CF. In physics terms, we say there are strong cohesive forces between them. i) H H ii) H H C = C C – C H H H H iii) H CH 3 iv) Cl H C C C – C ... Write down the repeating unit of polythene ii) Write down the formula for the monomer polythene. We can represent the addition polymerisation reaction of tetrafluoroethene in a number of different, but equivalent, ways: Relevance. 2. Answer: (B) Melamine. Draw The Structure Of The Monomer From Which Teflon Is Made. A b. Favorite Answer. Teflon: Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene. Teflon is used as a material resistant to heat & chemical attack. It is similar to polytetrafluoroethene (PTFE), except that it is a homopolymer of the monomer chlorotrifluoroethylene (CTFE) instead of tetrafluoroethene. The IUPAC name of CF = CF is tetrafluoroethylene . C. PET. The commercial production of nylon 6 starts with caprolactam that use an open-ring A. Teflon. Ans. The monomeric repeating unit of nylon 6, 6 is [NH – (CH 2) 6 - NH – CO – (CH 2) 4 – CO], which is derived from hexamethylene diamine and adipic acid. Only I b. It can tolerate heat better than other plastics. PTFE is one of a class of plastics known as fluoropolymers. Polychlorotrifluoroethylene (PCTFE or PTFCE) is a thermoplastic chlorofluoropolymer with the molecular formula (CF 2 CClF) n, where n is the number of monomer units in the polymer molecule. It has the lowest water vapor transmission … The discovery of PTFE actually happened completely by accident. Polyester, a class of synthetic polymers built up from multiple chemical repeating units linked together by ester (CO-O) groups. nylon a. Polytetrafluoroethylene (Teflon) has a repeat unit with the formula F2C—CF2. The brand name is Teflon, but its correct chemical name is polytetrafluoroethene (PTFE). B. Melamine. The brand name of this compound is Teflon: the slippery surface that prevents eggs from sticking to the pan. Nylon and Teflon are manmade synthetic polymers that are most widely used in the polymer industry. iv) To which type of hydrocarbon does the polythene belong. I. polypropylene II. Dacron consists of polymerized units of the monomer ethylene terephthalate, with repeating (C 1 0 H 8 O 4 ) units. (b) Determine the number-average molar mass of the sample. Teflon III. In structure-based nomenclature of polymers, the name of the repeating structural unit is enclosed within round brackets and the prefix "poly" is added at the start. Summary: Nylon vs Teflon. All Organic Chemistry Practice Problems Free Radical Polymerization Practice Problems. The repeating structural unit of most simple polymers not only reflects the monomer(s) from which the polymers are constructed, but also provides a concise means for drawing structures to represent these macromolecules. See the answer. Teflon is the chemical found in some brands of saucepans that helps to prevent your meal from sticking to them during the cooking process. 1 Answer. 1450 Views. A sample of the polymer consists of fractions with the following distribution of chains: (a) Determine the molar mass of each fraction. Due to the strength of carbon - fluorine bond , it is non reactive in nature . This problem has been solved! (iii) Bakelite- the monomeric unit present is formaldehyde (HCHO) & phenol (C 6 H 5 OH). I. polypropylene II. All you need to do is find the molar … Abhishek Bhardwaj 2019-02-12 05:31:50. Anonymous. 3. Answer . So instead of having a double bond between this Mount America unit, we now have single bonds that extend out and are basically constantly repeating this glory or carbon and Florian bond linkage.
