Answer:
Step-by-step explanation:
A. The reaction between cyclopentanone and ethylamine in the presence of a trace amount of acid would likely result in the formation of an imine. The specific product would be N-ethylcyclopentan-1-imine.
B. The reaction between cyclopentanone and diethylamine in the presence of a trace amount of acid would likely lead to the formation of a different imine. The specific product would be N,N-diethylcyclopentan-1-imine.
C. The reaction between acetophenone and hexylamine in the presence of a trace amount of acid would likely produce an imine. The specific product would be N-hexylacetophenoneimine.
D. The reaction between acetophenone and cyclohexylamine in the presence of a trace amount of acid would also result in the formation of an imine. The specific product would be N-cyclohexylacetophenoneimine.
