Unpaired electrons resonance with allylic double bonds. The arrow pattern of radical resonance is given below (f)

Explanation of Solution

The radical resonance structure of the given molecule

The radical resonance structure of the molecule is given below.

An unpaired electron occupies the allylic position and in is involving in resonance. Here three fishhook arrows were used to show the resonance.

The radical resonance structure of the molecule is given below.

An unpaired electron occupies the allylic position and in is involving in resonance. Here three fishhook arrows were used to show the resonance. The resulting resonance structure exhibits an unpaired electrons, the unpaired electrons allylic to another π bond that also involving resonance. Again three fishhook arrows were used for the resonance.
