Under hydrolytic conditions, the compounds used for the preparation of linear polymer and for chain termination, respectively, are

Options

  1. AC H 3 S i C l 3 and S i C H 3 4
  2. BC H 3 2 S i C l 2 and C H 3 3 S i C l
  3. CC H 3 2 S i C l 2 and C H 3 S i C l 3
  4. DS i C l 4 and C H 3 3 S i C l

Correct answer

B. C H 3 2 S i C l 2 and C H 3 3 S i C l

Step-by-step solution

For linear polymer, we need R 2 S i C l 2 and for termination, we need R 3 S i C l .
