Product of cyclohexanone/benzaldehyde with a substituted amine?

Answer 1

You should get an imine: #R-C=NR'_2#

A primary amine, #RNH_2# should react with an aldehyde, #R'C(=O)H# according to the following equation:
#RNH_2 + H(O=)CR' rarr RN=C(H)R' + H_2O# #(i)#

Additionally, using a ketone:

#RNH_2 + (O=)CR'R rarr RN=C(H)R'R + H_2O# #(ii)#

The formation of an imine from a ketone to give a ketimine is a little bit harder; you may have heat under reflux and remove the water produced; the carbonyl on the ketone is much more sterically hindered than the aldehyde. Both unsaturated nitrogen compounds tend to be a little bit unstable, so they are usually used directly. Reaction (i) is usually very facile; sometimes you do not even need to use solvent, and you just add amine to aldehyde and remove the water.

Answer 2

The product of the reaction between cyclohexanone/benzaldehyde and a substituted amine would be an imine or Schiff base.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
