. With detailed answers and explanations for each chapter, students can strengthen their understanding and prepare confidently for exams. Ideal for CBSE and other board students, this resource will simplify your study experience.Write the name and structure of one of the common initiators used in free radical addition polymerisation.
For polymerization reaction, an initiator is required. The initiator may be an cation, anion or free radical. So the type of polymerization in which free radical is used as an initiator is known as free radical addition polymerization. The common free radical initiator used is benzoyl chloride.
The structure of benzoyl chloride is as follows:
The reaction between A and B is first order with respect to A and zero order with respect to B. Fill in the blanks in the following table:
| Experiment |
A/ mol L - 1 |
B/ mol L - 1 |
Initial rate/mol L - 1 min - 1 |
| I | 0.1 | 0.1 |

This structure is Benozoyl peroxide
That is the structure of benzoic peroxide
I think it is a structure of benzyl peroxide not benzyl chloride
But why only benzoyl peroxide is used??
Isn't this the structure of Benzoyl Peroxide?
