Why ChemVidya

Built by a PhD chemist & CSIR-NET-qualified educator — independent prep, not any official exam.

One bank, every exam

The same vetted chemistry questions are tagged for each exam — CSIR-NET, GATE, IIT-JAM, SET/SLET and govt posts — so you study from one growing bank, filtered to the exam you choose.

Real study engine

1–5 confidence ratings, spaced repetition that re-surfaces weak cards, selective replay of any confidence level, and a "cram weak cards" mode.

Worked explanations

Every MCQ shows the correct option, a step-by-step explanation, and a textbook source so you learn the concept, not just the answer.

Organized by chapter

Within each exam, questions are grouped by Organic, Inorganic and Physical Chemistry chapters, so you always know which topic you're strengthening.

Organic Chemistry · sample question
Which is the strongest acid?
Acetic acid
Chloroacetic acid
Dichloroacetic acid
Trichloroacetic acid ✓
Answer: Trichloroacetic acid (Cl3CCOOH)
Electron-withdrawing chlorine atoms stabilise the carboxylate conjugate base through the inductive effect, so acidity rises with each added Cl: trichloroacetic > dichloroacetic > chloroacetic > acetic.
