Chapter 21, Problem 38E

(a)

Interpretation Introduction

Interpretation: The functional groups present in the given compound needs to be identified.

  

Concept Introduction : Organic molecules have some structural features in addition to $\text{C}-\text{H}$ and $\text{C}-\text{C}$ bonds. Functional groups are defined as an atom or group of atom with characteristic physical and chemical properties. Functional group contains multiple bonds, hetero-atom or sometimes both the multiple bonds and hetero-atom.

Table given below gives information about some common functional groups:
