The primary objective of this book is to help students develop command over fundamentals and their application through challenging questions. In this book, only those problems have been selected, which in the opinion of Career Point Faculty team, are most important for mastering application of concepts. This book covers a variety of questions asked in the IIT JEE examination ~ be it MCQ (One or More than One correct choice), Numeric Response Type, Matrix match type, paragraph based questions etc. A mix of questions helps stimulate and strengthen question-solving skills of the student. The majority of questions are not easy; some of them are definitely difficult. We believe if you solve these questions on your own, you will achieve a higher degree of understanding of concepts. We would like to suggest that you should attempt this book only after you complete a chapter. This book is also used by Lakshya Batch students of Career Point to give a finishing touch to their preparation for JEE-Advanced Exam. We hope this book would immensely help genuine, hardworking students in sharpening their questions solving skills enabling them to achieve a seat in most prestigious colleges. We take this opportunity to express our deepest appreciation to CP Publishing team, who helped in the editing of the book. We will greatly appreciate if the users of this book will let us know about any errors or misprints that they may happen to encounter. We will incorporate the same in the subsequent editions. This book covers the complete Chemistry course for JEE Advanced.

Cracking JEE Main & Advanced requires skills to solve a variety of thought-provoking problems with requisite synthesis of many concepts and may additionally require tricky mathematical manipulations. A massive collection of the most challenging problems, the Selected Problems Series comprises of 3 books, one each for Physics, Chemistry and Mathematics to suit the practice needs of students appearing for upcoming JEE Main and Advanced exam. Ranjeet Shahi’s, 1500 Selected Problems Asked in Chemistry aims to sharpen your Problem-Solving Skills according to the exam syllabi, across 30 logically sequenced chapters. Working through these chapters, you will be able to make precise inferences while avoiding the pitfalls in applying various laws of Chemistry. The Step-by-Step solutions to the problems in the book train you in both- the general and specific problem-solving strategies essential for all those appearing in JEE Main & Advanced and all other Engineering Entrance Examinations or anyone who is interested to Problem Solving in Chemistry.

The fundamental outlines of the physical world, from its tiniest particles to massive galaxy clusters, have been apparent for decades. Does this mean physicists are about to tie it all up into a neat package? Not at all. Just when you think you’re figuring it out, the universe begins to look its strangest. This eBook, “Ultimate Physics: From Quarks to the Cosmos,” illustrates clearly how answers often lead to more questions and open up new paths to insight. We open with “The Higgs at Last,” which looks behind the scenes of one of the most anticipated discoveries in physics and examines how this “Higgs-like” particle both confirmed and confounded expectations. In “The Inner Life of Quarks,” author Don Lincoln discusses evidence that quarks and leptons may not be the smallest building blocks of matter. Section Two switches from the smallest to the largest of scales, and in “Origin of the Universe,” Michael Turner analyzes a number of speculative scenarios about how it all began. Another two articles examine the mystery of dark energy and some doubts as to whether it exists at all. In the last section, we look at one of the most compelling problems in physics: how to tie together the very small and the very large – quantum mechanics and general relativity. In one article, Stephen Hawking and Leonard Mlodinow argue that a so-called “theory of everything” may be out of reach, and in another, David Deutsch and Artur Ekert question the view that quantum mechanics imposes limits on knowledge, arguing instead that the theory has an intricacy that allows for new, practical technologies, including powerful computers that can reach their true potential.
