Print Calculator Pariodic Table apling leaming An unknown The melting point ofthe 2,4-dinitrophenylhydrazone derivative was found to be 147 was r ne to razone. Use the data from the table of literature values for hydrazone melting points to identity the originalcarbonyl. Name of carbonyl 2.4-dinitrophenylhydrazone Move the label with the name of the original unknown carbonyl in the box below. acetone benzaldehyde butanal 2-butanone heptanal 2-hexanone 2-methylbutanal propanal melting point 126 239 123 118 108 110 120 148 144 156 heptanal2-hexanone propanal benzaldahyde 2-methytbutanal butanal 2-butanone 2-pentanone 3-pentanone acetone 2-pentanone 3-pentanone Exit Previous O Check Answer 0 Next Hint

Explanation / Answer

I think it should be propanal as melting point for derivative of this carbonyl is 1480C closest to 1470C
