Chemical Reactions: SSC CGL Chemistry
Chemical Reactions has 16 questions in the SSC CGL Tier I bank: one from the 2023 shifts and 15 from the 2024 shifts, and none from the 2025 shifts. They describe a school experiment and ask its type or product, track oxidation and reduction, or ask a reaction's order. One page covers all three, with the textbook examples SSC uses.
The handout has every subtopic, worked example, formula and trap with answers shown. The formula sheet is the chapter’s formulas and traps alone, on one page.
