(a)

Interpretation Introduction

Interpretation:

The coupling product formed when given organic electrophile reacts with given organozinc compound in presence of ${\text{Pd(PPh}}_{\text{3}}{\text{)}}_{\text{4}}$ should be identified.

Concept Introduction:

Negishi reaction: It describes how the product obtained when organometallic compound containing $\text{Zn,}\text{Al}\text{and}\text{Zr}$ is coupled with organic electrophile in presence of palladium or nickel catalyst.
