Identify the group from what you see. Use the distinguishing-test finder for “give a chemical test to distinguish…” questions, revise with flashcards, and open any card for the chemistry behind the colour and exam practice.
Pick a pair. The test, what each compound does, and the one-line reason you should write in the answer.
Say the answer aloud, then flip. Cards you mark “review again” come back later in the deck. Keys: Space flip, 1 knew it, 2 review again.
Exam focus tags are a guide to where each test is most often asked (Boards = CBSE/NCERT textbook and lab manual).
Filter by functional group or search a reagent (Tollens’, Fehling’s, Lucas…). Tap a card for the reason and practice questions.
