Chapter 21: Problem 6

The IR spectra of a compound helps in (a) providing the identify of compounds (b) showing the presence of certain functional group in the molecules (c) neither of the above (d) both of the above

Short Answer

Expert verified
The correct answer is (d) Both of the above.

Step by step solution

01

Understanding of Infrared (IR) Spectra

Infrared (IR) spectroscopy is a technique used for the identification and study of molecules by infrared absorption. These spectra can provide valuable information about the molecular structure of a compound, such as the identification of functional groups.
02

Option (a) Analysis

The IR spectra can indeed be used to provide the identity of compounds. Different substances have different spectra, and the range of frequencies they absorb is directly related to their molecular structure. Therefore, option (a) is correct.
03

Option (b) Analysis

The IR spectra can also be used to show the existence of certain functional groups in molecular structures. Different functional groups will absorb different wavelengths of infrared light, allowing us to identify them in complex molecules. Thus, option (b) is also correct.
04

Options (c) and (d) Analysis

Given that both option (a) and (b) are correct, option (c) stating 'neither of the above' is incorrect, and option (d) stating 'both the above' is correct.
