CHM345H5 Lecture Notes - Lecture 2: Aldehyde, Hydrolysis, Hemiacetal

1).use the melting points of your aldo-dehydration product (4-methylbenzaldehyde) and the derivative (cyclopentanone) to detamine their identity.

a). Does NMR spectrum of your aldo-dehydration product (4-methylbenzaldehyde) support these identifications. Explain your reasoning.

b). draw the structure of your aldo-dehydration product (4-methylbenzaldehyde) and write a balanced equation for its formation.

c).write equations for the formation of your hydrazones using the structures of your identified aldehyde (4-methylbenzaldehyde) and ketone (cyclopentanone).

Why does benzaldehyde does not react with itself during an aldol dehydration reaction?
