Polyamides

Assertion (A) Polyamides are best used fas fibres because of high tensile strength. Reason (R ) Strong intermolecular foces (like hydrogen bonding within polyamides) lead to close packing of chains and increase the crystalline character hence , provide high tensile strength to polymers

Polyamide is

A polyamide synthetic polymer prepared by prolonged heating of caprolactum is:

The condensation polymer are those which gives out some simple molecules like H_(2)O in course of reaction. Mostly in this reaction functional group changes. Polyamide is

Protein are nitrogeneous organic compound having very high molecular mass. They are polyamides formed from alpha -amino acid. The bond formed between two amino acid is called peptide bond -underset(O) underset(||)C-NH- . The product obtainded by this peptide bond formation are called peptide and they may be divided as di, tri ,tetra, penta peptide. The given structure of amino acid will exist at which pH?
