10. To be a heterocycle amine, the product must contain a heterocycle amine as well an amine group. In the given option (b) doesn't contain a heterocycle ring thats why we can not put this in the heterocyclic amine category.

12. The reaction of amine and water is a acid base reaction, here amine acts as a base and accepts a proton from water.

14. Generally alcohals have higher boiling point than the amines as they they have the stronger hydrogen bonding and in alcohals, bp increases as the molecular weight increases because of more vanderwall interactions.
