Chemistry 1 Marks Question

In cyclohexanamine, the lone electron pair of nitrogen is easily available because there is no resonance in it, whereas in benzenamine (aniline), the lone electrons pair of nitrogen is not easily available due to resonance, hence cyclohexanamine is more basic than aniline.

Ethanamine easily forms inter molecular hydrogen bonds with water, hence it is completely soluble in water. Due to the large, size of the phenyl group in aniline, it is unable to form hydrogen bonds with water, hence it is almost insoluble in water.
