(b)
Interpretation:
The curve arrow should be drawn for showing the movement of electrons.
Concept introduction:
Nucleophile: A Nucleophile carries electron pair (negative charged anion) on the molecule and it attacks the positive charged ions to form a chemical bond in reaction.
Electrophile: Electrophiles are neutral or positively charged species having empty orbitals that are attract by the electron rich centre.
Carbocation: Carbocation is a positive charged species and vital intermediate in organic synthesis and its movement depends on the stability of the intermediate and the product formation.
