A polymer with the high chemical stability has M.P: 3270C and the density of complete crystalline sample is 2.3 g/cm3 it can be
Teflon has high stability
Assertion: Teflon has high thermal stability and chemical inertness. Reason: Teflon is a thermoplastic.
A white crystalline solid “X” gives following chemical tests:
(i) it liberates CO2 with NaHCO3
(ii) It forms a coloured dye on diazotisation and coupling with β - napthol
(iii) With Br2 water it forms white ppt of 2, 4, 6 – tribromo aniline. Then "X" can be :
