PROBLEM Predict the product(s) and propose mechanisms for the following reactions: 19-34 (a) HCL H₂O CH3 (b) CH3-N CH3 HCL ? H₂O

please give me the correct answers!

Acid-Catalyzed Nucleophilic Addition - Addition of Amines: Imine and Enamine Formation (mechanism!) 1° amines add to form imines (C=NR), and 2° amines yield enamines (R₂N-C=C) CH,CH,NH2 H30* + H* - H₂O - Alcohols Addition to yield hemiacetals (hemiketals), acetals (ketals) -C(OR')2 (mechanism!) H30Ⓡ + N-H CH3CH₂OH (2 equiv.)
