This is the National Council of Educational Research and Training (NCERT) chemistry textbook for Class XII, Chemistry Part I — the first of the two-volume Class 12 chemistry set. It is an English medium (Roman script) book — the complete text, formulae, worked examples and exercises are in English, and there is no Hindi content in it. It is prescribed for CBSE schools and for state boards that follow the NCERT curriculum.
Part I carries the physical and inorganic chemistry portion of the Class 12 course. It opens with solutions — concentration terms, Raoult's law, ideal and non-ideal behaviour, and the colligative properties used to determine molar mass. Electrochemistry follows, covering electrode potential, the Nernst equation, conductance and its measurement, batteries, fuel cells and corrosion. Chemical kinetics deals with rate of reaction, order and molecularity, integrated rate equations and the Arrhenius equation. The inorganic half takes up the d- and f-block elements — the transition series, their general trends, important compounds, and the lanthanoids and actinoids — and closes with coordination compounds: Werner's theory, nomenclature, isomerism, valence bond and crystal field theory.
These are the chapters that carry the numerical weight of the Class 12 chemistry paper, and the reason to work from the prescribed text is straightforward: the derivations, the constants and the worked examples in the board paper come from here. For NEET and JEE candidates the same chapters are among the highest-yielding in the syllabus — solutions, electrochemistry and chemical kinetics are formula-and-application topics where a candidate either has the concept or does not, and coordination compounds is a standing source of questions on nomenclature, isomer counting and crystal field splitting. Coaching material adds drill; it does not replace the source text the questions are set on.
The book is supported by diagrams, data tables, solved intext examples worked step by step, intext questions placed through each chapter and a full exercise set at the end. Note that this is Part I — the organic chemistry chapters, including haloalkanes and haloarenes, alcohols, phenols and ethers, aldehydes, ketones and carboxylic acids, amines and biomolecules, are in Part II, and both volumes are needed for the complete Class 12 syllabus.

यह पुस्तक राष्ट्रीय शैक्षिक अनुसंधान और प्रशिक्षण परिषद (NCERT) द्वारा कक्षा XII (कक्षा 12) के लिए निर्धारित रसायन विज्ञान की पाठ्यपुस्तक Chemistry Part I है। ध्यान दें: यह पुस्तक पूर्णतः अंग्रेज़ी भाषा एवं रोमन लिपि में है — इसमें हिन्दी भाषा का प्रयोग नहीं है। इस भाग में भौतिक एवं अकार्बनिक रसायन के अध्याय सम्मिलित हैं — विलयन (सांद्रता, राउल्ट का नियम, अणुसंख्य गुणधर्म), विद्युत रसायन (इलेक्ट्रोड विभव, नर्नस्ट समीकरण, चालकता, सेल एवं संक्षारण), रासायनिक बलगतिकी (वेग, कोटि, समाकलित वेग समीकरण, आरेनियस समीकरण), d एवं f-ब्लॉक तत्व (संक्रमण तत्व, लैंथेनॉयड एवं ऐक्टिनॉयड) तथा उपसहसंयोजन यौगिक (वर्नर सिद्धांत, नामकरण, समावयवता, संयोजकता आबंध एवं क्रिस्टल क्षेत्र सिद्धांत)। आरेख, आँकड़ा-सारणियाँ, हल किए गए उदाहरण तथा अध्यायांत अभ्यास प्रश्न सम्मिलित हैं। CBSE बोर्ड परीक्षा का प्रश्न-पत्र इसी पुस्तक पर आधारित होता है, तथा NEET एवं JEE की तैयारी में भी ये अध्याय सर्वाधिक महत्त्वपूर्ण माने जाते हैं। ध्यान दें कि यह भाग-I है; कार्बनिक रसायन के अध्याय भाग-II में हैं — सम्पूर्ण पाठ्यक्रम हेतु दोनों भाग आवश्यक हैं।
