Question
I need help with the mass spec problem 2
I need problem 2 solved like the example 1 and to say what fragmination is most favorable
and explain why like in example 1

This tragmentation is more favorable because a primany radical is
more stable than a methyI radical.
when answer such questians, it is best to look at tuwo possible
frogmentation paths to analyze &compare the types of radicals
carbocations that are produced, Always go with the path that offers
a more steeble carbocation andlor radičal. For this example, since
both produced 2° carbocation, the focus was on the types of radicals
is what it would (0ok like:
