(a)

Interpretation Introduction

Interpretation:

The coupling product obtained by treating the given electrophile with given organoboron compound in presence of ${\text{Pd(PPh}}_{\text{3}}{\text{)}}_{\text{4}}$ should be identified.

Concept Introduction:

Suzuki reaction: It involves coupling of an aryl, a benzyl or vinyl halide with organoborane in presence of ${\text{Pd(PPh}}_{\text{3}}{\text{)}}_{\text{4}}$.

(b)

Interpretation Introduction

Interpretation:

The coupling product obtained by treating the given electrophile with given organoboron compound in presence of ${\text{Pd(PPh}}_{\text{3}}{\text{)}}_{\text{4}}$ should be identified.

(c)

Interpretation Introduction

Interpretation:

The coupling product obtained by treating the given electrophile with given organoboron compound in presence of ${\text{Pd(PPh}}_{\text{3}}{\text{)}}_{\text{4}}$ should be identified.

Concept Introduction:

(d)

Interpretation Introduction

Interpretation:

The product obtained by treating the given alkene with ${\text{CH}}_{\text{2}}{\text{I}}_{\text{2}}\text{and}\text{Zn-Cu}$ should be identified.

Concept Introduction:

Simmons–Smith reaction: It involves reaction of alkenes with organozinc reagent that is ${\text{ICH}}_{\text{2}}\text{ZnI}$ which results in formation of three–membered ring. This is a concerted reaction in which the configuration of starting alkene is preserved.

Interpretation:
