(a)
Interpretation:
The reason for the streak formation on silica gel TLC plates by carboxylic acids and addition of acetic acid to reduce the streaking should be explained.
Concept Introduction:
Thin Layer Chromatography is a sensitive chromatographic technique which used to analyze small quantities of the samples by solid-liquid adsorption method. Rectangular glass plate is coated with an adsorbent, sample to be analyzed is run on the plate in the developing chamber with the mobile phase to give spots of the analyzed sample.
(b)
Interpretation:
The chemical component which has to use to reduce the streaking on the TLC caused by the amine should be identified.
