see vanadium pentoxide reacting with napthalene is not at all a simple reaction it needs specific temperature of 623k

when V2O5 reacts with napthalene PTHALIC ANHYDRIDE IS FORMED

AND 1 WATER MOLECULE IS REMOVED

so the mechanism here reqired is nothing but a electrophilic substitution because the para group of carbon in the benzene is nucleophilic in nature so oxygen will attack there and cause the removal of water molecule and like this followed by meta and ortho group will also follow the same and then 3 ixgen atoms of V2O5 will form anhydride and remaining 2 oxygen molecules reacts with 4 hydrogen atoms and form water molecule

THANK YOU VERY MUCH FOR ASKING SUCH A BEAUTIFUL QUESTION

best of luck for your future
