Question

What spectral differences in Infra-Red absorption would be evident between a ketone and its 2.4-DNPH derivative? loss of carbonyl peak loss of carbonyl peak, gain of imine peak loss of carbonyl peak, gain of imine and amine peaks carbonyl peak retained but at lower frequency Which of the following molecules is least likely to produce a DNP-derivative with a narrow melting-point range? 2-hptanone 4-heptanone heptanal cyclopentanone Derivatization of aldehydes and ketones by DNP is an acid-catalyzed process. Explain why this conversion is actually hindered by the presence of too much acid. At very low pH, much more of the amine is protonated and can no longer function as an electrophile. At very low pH, much more of the carbonyl oxygen is protonated and can no longer function as a nucleophile. At very low pH, much more of the amine is protonated and can no longer function as a nucleophile. At very low pH, much more of the carbonyl oxygen is protonated and can no longer function as an electrophile

Explanation / Answer

5. Answer: Loss of carbonyl peak, gain of imine and amine peaks.

As per chegg guide lines, i done 1st question.

Thank you
