Question 1 options: at lambda max impurities in the sample do not absorb any light Because the allura red dye absorbs red color at 504 nm at lambda max the absorbance is the most sensitive to dye concentration at lambda max the absorbance is the least sensitive to dye concentrationHow can you distinguish aldehydes, esters and carboxylic acids using IR spectra? Explain using specific examples.
