$2$a$.$ Consider the reactions below:

$55\%$ trans $/45\%$ cis

Based on the product of the second reaction, which is more stable the trichloromethyl radical or the bromine radical.

Explain how the reaction result allowed you to determine the answer:

$2$b$.$ Propose a complete mechanism for the second reaction.

$2$c$.$ Explain why the first reaction yields a mixture of the trans$-$ and cis$-$products:
