Paragraph for Question 12 - 14 
The Organic compounds undergo various types of reaction. Such as Electrophilic addition, Nucleophilic 
substitution, Electrophilic substitution etc. The characteristic reaction of an organic compound depends on nature 
of functional group, stability of intermediate and reaction conditions.
