Chapter 21.4A, Problem 21.2P

Interpretation Introduction

Interpretation: The characteristics of methyl benzoate spectrum that rule out an aldehyde or carboxylic acid functional group by giving absorption at $1723{\text{cm}}^{-1}$ are to be stated.

Concept introduction: A method by which structure of compound is determined by the interaction between matter and electromagnetic radiation is called spectroscopy. A spectroscopic technique, in which infrared radiation is used for structural study is called IR spectroscopy.

To determine: The characteristics of methyl benzoate spectrum that rule out an aldehyde or carboxylic acid functional group by giving absorption at $1723{\text{cm}}^{-1}$.
