(iii) Thermoplastics: These are polymers in which the intermolecular forces of … This forces create a intermolecular bond called “hydrogen bond”. ... (e.g: water)- transported away from the rxn-larger molecule- dimer e.g: Nylon 66-dimer propagates by further reaction of either its amine end (-NH2) with another adipic acid molecule or its carboxylic acid end (-COOH) with another diamine molecule. These forces are intermediate of the forces present in the elastomers and in the fibres. Intermolecular force present in nylon-6, 6 is. 3 Thermoplastics- they have intermolecular forces intermediate between elastomers & fibres.Eg polythene ... On the basis of magnitude of intermolecular forces present in polymers, they are classified into the following groups: (i) Elastomers ... nylon 6, 6 is formed by condensation … Fibres are the polymer which have strong intermolecular forces between the chain.These forces are either hydrogen bonds or dipole dipole interaction . Condensation polymers: These are the polymers having very weak intermolecular forces of … 1.8k VIEWS. Which intermolecular force is important for the function of the antibiotic vancomycin. If the answer is not available please wait for a while and a community member will probably answer this Under this category, the polymers are classified into the … are solved by group of students and teacher of Class 12, which is also the largest student These forces are either hydrogen bonds or dipole-dipole interactions. Apart from being the largest Class 12 community, EduRev has the largest solved The fibres are crystalline in nature and have sharp melting points. community of Class 12. over here on EduRev! Because of that, these polymers show sharp melting points. ... in domestic … Selina Concise Mathematics Class 10 ICSE Solutions 2020-21, Human Eye and Colourful World Class 10 Extra Questions with Answers Science Chapter 11, Download Social Science Notes PDF for CBSE Class 6 to Class 10 Quick Revision, Science Notes | Quick Revision Notes for CBSE Class 6 to Class 10 Science – Free PDF Download, Download CBSE Maths Notes for 6 to 12 Classes | NCERT Maths Quick Revision Notes for Class 6 to 12 Free PDF, MCQ Questions for Class 11 Economics with Answers Chapter Wise PDF Download, Download All Chapters Social Science NCERT Solutions Pdf for Class 6 to Class 10, Science NCERT Solutions Class 6 to Class 10 Chapterwise Free PDF Download, Downlaod Free NCERT Solutions for Class 6 to Class 12 Maths | NCERT Maths Textbook Solutions PDF, Free Class 11 & Class 12 Chapterwise Physics NCERT Solutions PDF Download, Concise Mathematics Class 10 ICSE Solutions. EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something. Another example is PET. Among the following polymers, the strongest intermolecular forces of attraction are present in 1) Elastomers 2) Fibres 3) Thermoplastic 4) Thermosetting polymers 32. Intermolecular Forces - Chemistry, Class 11. In this scenario, intermolecular forces between the solvent and monomer subunits dominate over intramolecular interactions. hydrogen bonding. Can you explain this answer? Intermolecular force present in nylon-6, 6 is. 2 Fibres- thay have strong hydrogen bond or dipole dipole interactions between polymers chain.Eg nylon 66. Notice that this already contains an amide link. [JIPMER 1997] A) Vander Waals done clear. Question 21. peptide. B) They have a high degree of cross-linking by … What do you understand for 6&6 in Nylon -66 ? Discuss the main purpose of vulcanisation of rubber. These forces also lead to close packing of chains and thus give crystalline nature. Correct answer is option 'B'. In a bad solvent or poor solvent, intramolecular forces dominate and the chain contracts. (iii)Thermoplastics:- In this type of polymers interaction forces in between molecules are intermediate between elastomers … These forces are intermediate of the forces present in the elastomers and in the fibres. Thermoplastic polymers are those polymers which contain intermolecular forces higher than Elastomers but less than Fibers. By continuing, I agree that I am at least 13 years old and have read and T/F DNA molecules contain "codes," from which proteins and other materials can eventually be synthesized. These forces also bind the polymer chains. Example: Tg ( PP) Tg (PE) Since substitution of H in PE by CH 3 group in PP impedes the Because of the strong forces, the chains are closely packed, giving them high tensile strength and less elasticity. Among cellulose, poly (vinyl chloride), nylon and natural rubber, the polymer in which the intermolecular force of attraction is weakest is 2:37 10.4k LIKES Among the following, the weakest interparticle forces of attraction are present in 1) Thermosetting polymers 2) Thermoplastic polymers Answers of Which intermolecular force is present in Nylon 6,6?a)Copolymersb)Hydrogen bondingc)Dipole-dipole interactiond)van der Waals forcesCorrect answer is option 'B'. Q16.Arrange the following Polymers in increasing order of intermolecular force. The elasticity of rubber increases and it remains so over a wide temperature range. Based on Molecular forces : The properties of polymers are governed by intermolecular forces, e.g., Van der Waal’ s forces and hydrogen bonds, present in the polymer. The bond found in Nylon-66 is a(n) _____ bond. Can you explain this answer? ... Nylon 66, Dacron, etc. A few examples of this class are nylon-66, terylene and polyacrylonitrile. 3) Nylon 4) Natural rubber 31. (ii) Fibers:- In this of polymers monomers are held together by strong intermolecular forces like hydrogen bonding. 7. These follow the order : ... intermediate of the forces present in the elastomers and in the fibres. Number of atoms present in a (i) ... - In this type of polymers chains are held together by the weakest intermolecular forces. C) Dipole-dipole interaction done clear. (ii) Nylon – 6, Neoprene, Polyvinyl chloride. Nylon - 2 nylon - 6 is … (ii) Neoprene < polyvinyl chloride < Nylon 6. The common examples are nylon-66, dacron, and silk. These polymers possess intermolecular forces of attraction intermediate between elastomers and fibres. Synthetic polymer- Polythene, Nylon 6,6, BunaS, Teflon, PVC (any one) b) Thermoplastic polymers – These are linear or slightly branched long-chain molecules capable of repeatedly softening on heating and hardening on cooling. Nylon 66 is formed through condensation polymerization whereby water is eliminated from the process. Fibrous polymers. Answer: 1. (i) Nylon – 66, Buna-S, Polythene. The fundamental elements of these interactions are the dipole moment (uneven charge distribution within a molecule) and Polaris ability (the relative tendency of charge redistribution within a molecule imparted by an electric field). It makes rubber resistant to wear and tear. When this molecule polymerises, the ring opens, and the molecules join up in a continuous chain. Nylon-66,Buna-S,Polythene Ans:Buna-S
