The correct answer is
The correct answer is
- A(a)
- Correct answerB(b)
- C(c)
- D(d)
Solution
(A-II) Neoprene is prepared from chloroprene.
Neoprene is synthetic rubber or elastomer and used in laptop sleeves, orthopedic braces,electrical insulation and automotive fan belts. (B-III) Monomer unit of nylon-6, 6 are adipic acid and hexamethylene diamine.
Nylon- 6,6 is fiber and used in airbags, apparel, carpet fibers, oil pans, ball bearing cages, radiation tank etc. (C-IV) High density polyethene (HDP) is prepared in presence of Ziegler-Natta catalyst. It is more harder and opaque and can withstand some what higher temperature for short time periods. (D-I)
Melamine formaldehyde resin used in kitchen utensils and plates. It is also used in formation of decorative paper. Melamine-formaldehyde resin tightly packed by cross-linked network.
