This is another doubt from M and B.
A mixture of 1 mole of cyclohexane, 1 mole of benzaldehyde and 1 mole of semicarbazide were reacted. On immediately isolating the product, we got the semicarbazone of cyclohexane almost 100%. But on isolating the product after several hours, we got the semicarbazone of benaldehyde almost 100%.
Explain.
