This section focuses on numerical, quantitative, and data-based problems related to aromatic compounds and electrophilic aromatic substitution (EAS) reactions. It is designed for Class 11–12 students, competitive exam aspirants, and undergraduate learners to apply aromatic chemistry concepts through calculations, rate comparisons, and data interpretation.
In this section, you will practice:
Numerical problems based on reaction rate comparisons in EAS
Quantitative analysis of activating and deactivating substituent effects
Data interpretation from experimental reactivity tables
Problems involving energy profiles and σ-complex stability
Calculation-based comparison of ortho, meta, and para substitution outcomes
Graph- and table-based problems related to aromatic reactivity
NCERT-aligned numerical and logic-based exam questions
The content is structured to improve quantitative reasoning, enhance data interpretation, and help students confidently handle numerical and analytical questions in school examinations, JEE-type exams, and undergraduate assessments.
Develop accuracy and confidence in solving numerical applications related to aromatic compounds and electrophilic substitution through systematic and exam-focused practice.
Q. In the nitration of toluene, which product is formed predominantly?
A.
Nitrotoluene (ortho)
B.
Nitrotoluene (para)
C.
Dinitrotoluene
D.
Benzyl nitrite
Solution
The para-nitrotoluene is formed predominantly due to steric hindrance at the ortho position.
Q. Which position on a disubstituted benzene ring will a new substituent most likely attach if one substituent is a strong electron-donating group and the other is a weak electron-withdrawing group?
A.
Ortho
B.
Meta
C.
Para
D.
None
Solution
The new substituent will most likely attach at the ortho position due to the activating effect of the electron-donating group.
