Draw the curved arrows to complete the given radical reaction mechanism involving bond breaking. There is a scheme of a reaction where CHCH3 with a benzene ring and an OCH3 group attached to the first (from left to right) carbon atom decomposes into an OCH3 radical and CHCH3 with a benzene ring attached to the first (from left to right) carbon atom and an unpaired electron on the first carbon atom. The reactant has two electron pairs at the O atom. The OCH3 radical has two electron pairs and one unpaired electron on the O atom.
