Question

Match the following:

(i) Biodegradeable polymer	(p) 3-hydroxybutanoic acid
(ii) Bakelite	(q) Phenol
(iii) Neoprene	(r) 2-chlorobuta-1,3-diene
(iv) Glyptal	(s) phthalic acid

• A. $\left(i\right)-\left(q\right);\left(ii\right)-\left(p\right);\left(iii\right)-\left(r\right);\left(iv\right)-\left(s\right)$
• B. $\left(i\right)-\left(p\right);\left(ii\right)-\left(q\right);\left(iii\right)-\left(r\right);\left(iv\right)-\left(s\right)$
• C. $\left(1\right)-\left(s\right);\left(ii\right)-\left(r\right);\left(iii\right)-\left(p\right);\left(iv\right)-\left(q\right)$
• D. $\left(1\right)-\left(p\right);\left(ii\right)-\left(q\right);\left(iii\right)-\left(s\right);\left(iv\right)-r)$

Answer 1

The correct option is B $\left(i\right)-\left(p\right);\left(ii\right)-\left(q\right);\left(iii\right)-\left(r\right);\left(iv\right)-\left(s\right)$

Poly-Beta-Hydroxybutyrate (PHBV) is obtained by the copolymerization of 3-hydroxybutyric acid and 3-hydroxypentanoic acid. PHBV is used in specially packaging orthopedic devices and in controlled release of drugs. PHBV undergoes bacterial degradation in the environment.
Bakelite : Phenol and formaldehyde
Neprene: 2-Chloro-1, 3-butadiene
Glyptal is a copolymer of ethylene glycol and phthalic acid
Option (a) is correct
