Given below are two statements : Statement I : Ethane at 333 to 343 K and 6-7 atm pressure in the presence of AlEt3 and TiCl4 undergoes addition polymerization to give LDP. Statement II : Caprolactam at 533-543K in H2O through step growth polymerizes to give Nylon 6. In the light of the above statements, choose the correct answer from the options given below :

1. Statement I is false but Statement II is true
2. Statement I is true but Statement II is false
3. Both Statement I and Statement II are true
4. Both Statement I and Statement II are false

Correct answer: Statement I is false but Statement II is true

Solution

Statement I is incorrect because ethane does not undergo addition polymerization under the specified conditions; it requires a different approach for polymerization. Statement II is accurate as caprolactam indeed polymerizes through a step-growth mechanism in water to form Nylon 6.
