I hate destroyer cuz it doesnt explain enough.
Destoyer OCHEM #4

this is condensations of amines with ketones.
it could be answer A or B since both ends of this amine is primary amine.

can anyone tell me y the answer is B not A?

ya i was trippin ballz on this one too... but look closely.... the right sides is a primary amine, but the left sides is a primary AMIDE

Its explained pretty well, you have to pay close attention to detail which is tough when reading explainations. as ash said, the AMINE(NH2) group is what is reactive. The AMIDE (NH2-C=0) doesnt partake in this rxn.
