Identify the chain initiation step of the polymerisation of ethene in the presence of benzoyl peroxide initiator, from the following?
A. C6H5• + C2H4 = C6H5-CH2-CH2•
B. C6H5-CH2-CH2• + C2H4 = C6H5-CH2-CH2-CH2-CH2•
C. C6H5-CH2-CH2-CH2-CH2• = C6H5-(-CH2-CH2-)n-CH2•
D. C6H5-(-CH2-CH2-)n-CH2• + C6H5-(-CH2-CH2-)n-CH2• = C6H5-(-CH2-CH2-)n-C6H5
