Question 21 Mark
Convert nitrobenzene into benzene.
Question 31 Mark
is more basic than benzenamine 
why?Answer
View full question & answer→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.
Question 41 Mark
Ethanamine is completely soluble in water, whereas benzenamine (aniline) is almost insoluble in water, why?
Answer
View full question & answer→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.
Question 51 Mark
Write the reaction sequence required to convert methanamine into ethane nitrile.
Question 61 Mark
Give the equation of reaction of aniline with Benzaldehyde.
