PREFACE
Once you have an idea of what you are going to be asked in a test, you are more
comfortable to tackle it, and your performance in the test improves dramatically.
Once you know the importance of different chapters and topics from the syllabi
for a exam by going through chapterwise and topical segregation of previous
years' questions, you can strategically plan out your preparation for the exam by
allotting your time accordingly for the chapters or the topics of the chapters.
This book Chapterwise & Topicwise Engineering Entrances Solved Papers
Chemistry has Previous Years' Engineering Entrance Questions with their Solutions
to fulfill the above mentioned needs of understanding the nature & pattern of
questions being asked in JEE Main & Advanced and other Engineering Entrances.
The Salient Features oft he Book are
• It covers all the questions with explanations from year 2005 to 2019 for all
engineering entrance exams in India (both National as well as Regional).
• Chapterwise division and topical categorisation has been done keeping in mind
the syllabi of various engineering entrance exams and NCERTTextbooks
• Questions of all engineering entrances are grouped according to the year.
• Extreme care is taken, while solving the questions and compiling their
explanations for their accuracy.
We hope that the book will be of utmost help to you in your studies, and propel
you to success in the engineering entrance exams. Suggestions for further
improvement are welcome.

QUICK REVIEW
Chemistry is that branch ofs cience which deals with the study Atomic Mass
of composition, properties and interaction of matter. Atomic mass is defined as a number that expresses as to how
Precision refers to the closeness of set of values obtained by many times an atom of the element is heavier than 1112th of
identical measurement while accuracy, refers to the the mass of carbon atom (12 C). Therefore,
closeness of a single measurement to its true value.

combinations. These are
(i) Law of conservation of mass Molecular Mass
(ii) Law of definite proportion Molecular mass is defined as the sum of atomic masses of the
(iii) Law of multiple proportion elements present in a molecule. Thus, it is obtained by
multiplying the atomic mass ofe ach element by the number of
