Question

1- instruments is most appropriate for confirmatory qualitative organic analysis?

A. Fourier transform infrared spectroscopy (FTIR)

B. Atomic emission spectroscopy (OES or AES)

C. Atomic absorption spectroscopy (AAS)

2- instruments is most appropriate for separation and analysis of a mixture of compounds in a biological matrix?

A. High performance liquid chromatography (HPLC)

B. Gas chromatography (GC)

C. Fourier transform infrared spectroscopy (FTIR)

Answer 1

1) Instruments is most appropriate for confirmatory qualitative organic analysis?

Ans: A. Fourier transform infrared spectroscopy (FTIR)

This is appropriate intrument for confirmatory of qualitative organic analysis.

Advantages of FTIR over OES and AAS

- small amount of sample quantity is required for analysis.

- each and every functional group is detected.

- results obtained are quick.

2- instruments is most appropriate for separation and analysis of a mixture of compounds in a biological matrix?

Ans: A. High performance liquid chromatography (HPLC)

Biological matrix have high melgting point so that they get degrade in GC and accurate results can't obtained but in HPLC biological matrix dissolves in appropiate solvent and can be separated as per their retention time and are detected.

FTIR is not used for separation but only for detection.
