Answer to Question #154358 in Organic Chemistry for SUDIP MONDAL

Question

The monoprotonation of adenine in acidic solution

Answer 1

Adenine is monoprotonated on the Nitrogen-7 position under acidic conditions to form a neutral adenine and a deoxyribose as the end products.

As the pH lowers, and acidity increases, the double protonation process occurs by the attack of excessive protons on the Nitrogen-3 position.
