Given below are two statements: Statement I: High density polythene is formed in the presence of catalyst triethylaluminium and titanium tetrachloride. Statement II: High density polymers are chemically inert. In the light of the above statements, choose the correct answer from the options given below:
A
Statement-I is correct but Statement-II is false.
B
Statement-I is incorrect but Statement-II is true.
C
Both Statement-I and Statement-II are true.
D
Both Statement-I and Statement-II are false.
Detailed Solution
High density polythene (HDPE) is indeed formed using a Ziegler-Natta catalyst (triethylaluminium and titanium tetrachloride) — Statement I is true. High density polymers, being tightly packed with strong intermolecular forces, are also chemically inert — Statement II is true. Both statements are correct, per NCERT.
