Q. Which of the following statements regarding semicarbazone formation from cyclohexanone and benzaldehde are incorrect?

Aldehydes Ketones and Carboxylic Acids

Solution:

Semicarbazone formation from cycloheanone is kinetically stable but thermodynamically less stable and vice versa for semicarbazone formation from benzaldehyde as the electronic effect activate the aldehyde group in cycloheanone but delocalisation of electrons in benzaldehyde makes the aldehyde group deactivate Hence, the secmicarbazone formation for cyclohexanone is more faster than that $f$ benzaldehyde
