BSc Physical Chemistry — Handwritten Notes (1st & 2nd Semester)
Every B.Sc chemistry student remembers the jump from higher secondary to undergraduate-level physical chemistry. The mole concept that felt comfortable in Class 12 suddenly expands into stoichiometry, eudiometry, and quantum mechanics. These 196 handwritten pages are designed to bridge that transition, covering the topics that appear in the first two semesters of most Indian university B.Sc programmes.
The material opens with classification of matter and atomic mass — topics that seem simple but form the foundation for everything downstream. From there, the notes move through the mole concept, ideal gas laws, mixture analysis, empirical and molecular formula determination, and the classical laws of chemical combination. Stoichiometry and POAC (principle of atom conservation) receive twenty-seven pages of dedicated treatment, which is appropriate given how heavily first-year exams weight numerical problems in this area.
Key Features
What sets these notes apart is the logical sequencing. Concentration terms — molarity, molality, normality, mole fraction — are introduced before titration and eudiometry, so when you reach those calculation-heavy sections, the vocabulary is already in place. The eudiometry chapter is a pleasant surprise; many textbooks gloss over gas analysis reactions, but these notes devote nine pages to the topic with worked examples.
The largest single block is atomic structure and quantum mechanics at seventy-seven pages. Schrödinger's wave equation, quantum numbers, orbital shapes, radial probability distributions, and nodal surfaces are all covered. This section alone makes the PDF worth downloading for first-year students, since most syllabi introduce quantum mechanics in the second semester and the topic appears again in later physical chemistry courses.

Who Should Read This
First-semester students should start from page one and work through sequentially — the notes are structured to build knowledge cumulatively. The stoichiometry and concentration terms sections will see the most use during first semester exams. Second-semester students will focus on the atomic structure block, which covers quantum mechanics from Schrödinger's equation through orbital shapes and probability distributions.
Second and third-year students can use this as revision material. Returning to mole concept fundamentals and POAC before tackling advanced thermodynamics prevents the calculation errors that come from rusty stoichiometry skills.
