1 chemical reaction
2 homolytic fission
3 resonance
4 hetrolytical fission​

Answer 1

Answer:

Fishhook arrows indicate cleavage or movement of a single electron shown as a single-headed curved arrow. They are widely used in radical chemistry to represent the hemolytic cleavage and reactions of radicals

Hope it is helpful to all

THANK YOU

Answer 2

FISH HOOK ARROW OR HALF HEADED ARROR IS USED TO SHOW RESONANCE .

Explanation:

• Half headed arrow or fish look arrow looks like ⇌
• they are mainly used to show the equilibrium reactions
• they shows that reaction is possible in either direction , it can be forward or backward.
• here the product can be converted into reactant and reactant can be converted into product.
• also shows in resonance that the both the structures are similar for example in benzene.
