Question

In nitration HNO₃ and H₂SO₄ act as:

• A. Both acid
• B. Both base
• C. HNO₃: acid and H₂SO₄: base
• D. HNO₃: base and H₂SO₄: acid

Answer 1

The correct option is D

HNO₃: base and H₂SO₄: acid

Solution:

• Nitration involves an electrophilic substitution reaction.
• The addition of Nitric acid and Sulphuric acid will lead to the nitration of the compound.
• Nitric acid acts as a lewis base due to the lone pair of oxygen.
• Sulphuric acid acts as a lewis acid by donating hydrogen cation.

So, the correct answer is option D.
