(a)
Interpretation:
Curved arrow and the product formed for the given nucleophilic addition step are to be drawn.
Concept introduction:
The curved arrow drawn from the nucleophile (electron rich species) to the polar pi-bond (electron poor species) represents the flow of electrons from an electron rich site to an electron poor site. The second curved arrow is drawn from the center of double or triple bond to the electronegative atom. A new bond is formed between the nucleophile and the electron deficient atom.
