PrefaceNT“Triumph Chemistry” is a complete and thorough guide to prepare students for MHT-CETexamination. The content of this book is based on the Maharashtra State Board Syllabus. This book includeschapters of Std. XII Sc. and selected chapters of Std. XI Sc. curriculum as per latest MHT-CET Paper Pattern.Quick Review which summarizes the important concepts of the entire chapter is provided for all the chapters.Formulae that form a vital part of MCQ solving are provided for relevant chapters.MCQs in each chapter are divided into three sections:Classical Thinking: consists of straight forward questions including knowledge based questions.TECritical Thinking: consists of questions that require understanding of the concept.Competitive Thinking: consists of questions from various competitive examinations like JEE, NEET (UG),MHT CET, KCET, GUJ CET, AP-EAMCET (Engineering, Medical), TS-EAMCET (Engineering, Medical),NAssam CEE, BCECE, WB JEE, etc.ECOHints have been provided in downloadable format to relevant MCQs and evaluation test which arebroken down to the simplest form possible.An Evaluation Test has been provided at the end of each chapter to assess the level of preparation of thestudent on a competitive level.Additional chapter Organic Reaction has been provided which includes MCQs based on various organicchemistry concepts.In order to understand how chemistry plays an important role in our day to day life, we have made anattempt to illustrate the same in the form of images/visuals in the related chapters.The journey to create a complete book is strewn with triumphs, failures and near misses.

TextbookChapter No.Some Basic Concepts of ChemistryQuick ReviewBranches of chemistry:PL Have you ever wondered what is the reference for 1kilogram? It has been defined as the mass of theInternational Prototype of the Kilogram. Theprototype is made of platinum-iridium (Pt-Ir)cylinder that is stored in an airtight jar atInternational Bureau of Weights and Measures inFrance. Pt-Ir was chosen because its mass remainsconstant for an extremely long time and it is resistantto the attack of different chemicals. This referencestandard is used to calibrate or standardize differentmeasuring devices such as analytical balances.EC1.9N1.8IntroductionImportance and scope of chemistryHistorical approach to particulate nature of matterLaws of chemical combinationDalton’s atomic theoryConcepts of elements, atoms and moleculesAtomic and molecular massesAvogadro’s law, Avogadro’s number and moleconceptPercentage composition and empirical and molecularformulaChemical reactions and stoichiometryO1. alloy as an International Prototypeof the KilogramSubtopicsTE01Chapter 01: Some Basic Concepts of ChemistryM Inorganic chemistryChemistrySAStudy of the composition,structure and properties ofmatter and the reactions bywhich one form of mattermay be converted intoanother form.Physical chemistryDeals with the structure of matter, the energy changes and the theories,laws and principles that explain the transformation of matter from oneform to another.
