KCET Entrance Exam Answer Keys For Chemistry
Study Solutions For KCET Entrance Exam For Chemistry
KCET is held every year and it aims to help students from all over the country become engineers. The competition among candidates is quite high and it requires you to be extra careful about how you study for chemistry. KCET exam syllabus for Chemistry has been prepared by NCERT in accordance with the syllabus prescribed for class 10th,11th and 12th.
KCET is a gateway to the topmost engineering colleges in Karnataka.
Since its formation in 1984, every year thousands of students appear for this entrance exam. Therefore, the competition is quite high and the students need to be extra cautious about how they study for chemistry. The main focus should be on how you are approaching your preparation rather than how many hours you study. Chemistry is one of the scoring subjects among the three that are tested in KCET. Therefore you must study smart to ace this subject and move one step closer to cracking KCET.
KCET Syllabus for Chemistry
KCET Syllabus for Chemistry (2018-19)
The KCET syllabus for Chemistry is divided into two parts - General Studies and Advanced Topics. The topics covered in General Studies are:
Atomic structure and bonding, periodic properties of elements, ionic compounds and ionic behaviour of ions etc.
Chemical equilibrium & thermodynamics, chemical kinetics/dynamics etc.
Organic chemistry from monomers to polymers with emphasis on functional groups such as benzene rings, aromatic rings etc., conjugated systems like alkanes (C5H10), alkenes (CnH2n+2) etc., organometallic compounds (metals + ligands)
As mentioned before, chemistry is a scoring subject so you should cover all the topics mentioned in the syllabus to get good marks and rank higher in KCET. The syllabus includes topics from class 10 and 11 as prescribed by NCERT. Let us discuss some important topics that have appeared in previous years' exams:
The NCERT books and other material are sufficient to score well in KCET. Some important topics and chapters that can be listed as follows:
Inorganic Chemistry, Coordination Compounds (Unit-1)
General Principles and Processes of Isolation of Elements (Unit-2)
Organic Chemistry Unit 1-3 (Unit 4-5)
Looking at previous years' questions
it is clear that NCERT books are sufficient to score well since most questions were asked directly from them. Some important topics and chapters can be listed as follows:
Looking at previous years' questions, it is clear that NCERT books are sufficient to score well since most questions were asked directly from them. Some important topics and chapters can be listed as follows:
Chemisty
General Chemistry (I) & 13A-13B – Chapter 1: Introduction to chemistry; Chapter 2: The mole concept; Chapter 3: Chemical reactions and their kinetics; Chapter 4: Atomic structure and bonding in molecules; Aqueous solutions and electrochemistry n=1 through n=7 (approximately); Gas laws n=1 through n=4 (approximately).
Inorganic Chemistry
Inorganic chemistry is the study of inorganic compounds. In this section, you will learn about the concept of oxidation, ionization and electrophilicity/anionicity. You will also be introduced to some important elements and their compounds such as carbon dioxide (CO2), sodium bicarbonate (NaHCO3), potassium hydroxide (KOH) and calcium chloride (CaCl2).
You will also learn about reactions involving these elements such as chlorination reaction which involves chlorine gas being added to water at high temperature causing hydrochloric acid to form along with other compounds such as HCl gas or H2O molecules depending upon how much heat was supplied by heating the mixture before adding chlorine gas into it
Coordination Compounds
Coordination compounds are formed by the binding of a metal atom to a number of ligands. The strength of these bonds depends on the coordination number, which is determined by how many ligands are bound to the central atom (i.e., 1d or 2d).
General Principles and Processes of Isolation of Elements (Unit-1)
This unit covers the concept of isolation of elements, methods for their isolation and uses.
The concept of isolation of an element is explained in this unit. The different methods for isolation are explained and their importance is also discussed.
The importance of isolating elements is discussed in this unit along with some examples where isolated compounds have been found to be useful as medicines or chemicals.
p-Block Elements (Unit-2) - Oxygen Family
Oxygen family - Oxidation numbers
How to balance equations?
How to solve problems?
Write balanced equations. Write unbalanced equations if required.
d- and f- Block Elements (unit-5) - d-block elements
The d- and f- block elements are both rare earth elements and transition metals. D-block elements include scandium, yttrium and lanthanum; f-block elements include actinium, thorium and protactinium. Both the d- and f-block are very similar to each other but still have their own unique characteristics:
They both have a high atomic weight (d=106)
They both tend to be metallic in nature with no flexibility in crystal structure
Organic Chemistry
Organic chemistry is the study of carbon compounds. It deals with the principles of organic reactions and their use in industry, medicine and biology.
Organic chemistry deals with the study of carbon compounds. Carbon is the most important element in this subject because it forms all life on earth including plants, animals and humans!
Conclusion
Looking at previous years' questions, it is clear that NCERT books are sufficient to score well since most questions were asked directly from them. Some important topics and chapters can be listed as follows:
