About Class 12 Chemistry PYQs
These are the official questions asked in CBSE Class 12 Chemistry board examinations from 2016–2025. CBSE conducts each board exam in multiple question paper sets — students in different regions receive different sets of the same exam. Padhify’s question bank combines every set of every year and removes repeated questions, which is why recent years show 100+ unique questions while a single set contains roughly 30–35.
Practising chapter-wise PYQs is the highest-return preparation strategy for boards: examiners reuse concepts, question patterns and even exact phrasing year after year. Every question here appears with its year and marks, so you always know its weight in the real exam.
