Question

Which carbon of  is predicted to be the major site of substitution when this alkene reacts with chlorine at 400 $\circ$ C?

Quizplus · Accepted Answer

The major site of substitution will be where the carbon-carbon double bond is located, which is between carbons II and III. Chlorine will add across this double bond to form a new carbon-chlorine single bond on both carbons II and III. This type of addition reaction is known as electrophilic addition. Therefore, carbon III in 11eaa4bc_3dc7_4dff_9180_cd7e6f7a4256_TB5902_00 is predicted to be the major site of substitution.
