  • Maximum two attempts in consecutive years are allowed in JEE Advanced.

Q.6: How to crack the Joint Entrance Examination (JEE)?

JEE is one of the toughest competitive entrance exams. A candidate has to prepare for JEE with dedication as the JEE syllabus is really extensive being an amalgamation of class 11th and class 12th syllabus. With tried and tested tricks, cracking JEE would become an easy task.

Q.7: How do I prepare simultaneously for JEE and board exams?

JEE Mains and 12th Board exams almost come at the same time without much gap. It restricts the student to prepare exclusively for JEE. Thus it is important to study for both board exams and JEE simultaneously.

Q.8: Which books are best for JEE preparation?

Preparation of JEE is a tough task. The syllabus is vast and there is too much to read. Added to this, there are lots of books that are available in the market which adds on to the confusion.

The above units cover around 60% of JEE Physics syllabus. Some of the important physics questions from the JEE point of view are given below:

  • Friction does fall under the important topics, which helps you in scoring for JEE. Following are the concepts that should be studied carefully:

Concepts of friction – What it is? How it affects us? Causes of friction, Types of friction (static friction, kinetic friction, rolling friction, fluid friction), Cause and direction of rolling friction, Coefficient of friction, the angle of repose, the angle of friction, differences between static friction and kinetic friction.

  • Which is the best book for JEE physics preparation?

Certain books like HC Verma for Physics vol I & vol II contains a very good selection of questions from practical applications of concepts which could prepare you well for the exam.

  1. Equilibrium
  2. Chemical Kinetics
  3. Redox Reactions and Electrochemistry
  4. Hydrogen
  5. s, p, d & f block elements
  6. Coordination Compounds
  7. Organic Compounds Containing Halogens, oxygen & Nitrogen
  8. Hydrocarbon

Q.9: Which is the best book for JEE chemistry preparation?

Refer NCERT textbook for class 12th, this book contains all the details in a very precise manner. A quick view of this chapter can help you to understand the fundamental concepts and their applications. Some of the important chemistry questions from the JEE point of view are given below:

According to JEE syllabus the significant topics in the atomic structure are:

Discovery of the electron, proton and neutron, Atomic models and Dalton’s atomic theory, Electromagnetic radiations, Quantum mechanical model of an atom, Dual nature of matter and the photoelectric effect, Electronic configuration. The topic of atomic structure covers 5-7% marks in chemistry paper and these topics require an understanding of the concepts and retaining important formulae.

  • Following is the general type of questions asked in JEE:

Calculate:

(a) The de Broglie wavelength of an electron moving with a velocity of 5.0 × 105 ms–1.

(b) Relative de Broglie wavelength of an atom of hydrogen and atom of oxygen moving with the same velocity (h = 6.63 × 10–34 kg m2 s–1)

(a) ? = hmv = 6.63 × 10?34 kgm2s?1 (9.11 × 10?31 kg) (5.0 × 105 ms?1) = 1.46 × 10?9 m Wavelength (?) = 1.46 × 10?9 m

(b) An atom of oxygen has approximately 16 times the mass of an atom of hydrogen. In the formula? = hmv, h is constant while the condition of the problem makes v, also constant. This means that? and m are variables and ? varies inversely with m. Therefore, ? for the hydrogen atom would be 16 times greater than ? for the oxygen atom.

Chemical Kinetics does fall under the important topics, which help you in scoring for JEE. Following are the concepts that should be studied carefully:

Rates of Chemical Reactions, Order of reactions, Rate constant, First order reactions, the Temperature dependence of rate constant (Arrhenius Equation).

  • Calculate the half-life for a first-order reaction if 68% of the reactant is reacted within 66 s.

68% of the reactant has been consumed implies that 32% remains, hence using the integrated equation for 1st order reactions: ln A = -kt + ln Ao ln 0.32Ao = – k (66) + ln Ao k = 0.0172642 s-1 This calculation is done, as you can with how much substance remains, not how much is used up.

The carboxylic acid is an organic compound containing a carboxyl group (COOH) attached to an alkyl or aryl group. The general formula of a carboxylic acid is Ar/R?COOH where Ar/R represents the aryl or alkyl group attached. In carboxylic acids, three of the four bonds of the carboxyl carbon atom are with two oxygen atoms.

  • Explain the physical properties of carboxylic acids?

Carboxylic acids have high boiling points as compared to aldehydes and ketones of comparable masses because of intermolecular hydrogen bonding. The simple aliphatic carboxylic acids are soluble in water due to the formation of hydrogen bonds in water. As the number of carbon atoms in carboxylic acids increases their solubility decreases due to an increase in the length of the hydrophobic group attached to the carboxyl group.

  • Explain the chemical properties of carboxylic acids?

Carboxylic acids are highly acidic in nature. Their acidity is higher than that of phenols and alcohols but lesser than that of mineral acids. They generally undergo four types of reactions:

  1. Reactions involving cleavage of O-H bond, for example, esterification of carboxylic acids.
  2. Reactions involving cleavage of C-OH bonds, for example, reaction with ammonia
  3. Reactions involving degradation of –COOH group, for example, decarboxylation
  4. Reactions involving substitution in the hydrocarbon part, for example, Hell-Volhard-Zelinsky reaction (halogenation).
  • What are the important topics in chemical bonding that needs to be focused in order to crack JEE?

According to JEE syllabus the significant topics in chemical bonding are:

Ionic bonding, Covalent bonding, Bond characteristics and Lewis theory, Hybridization, Valence bond theory, VSEPR theory, Molecular orbital theory, Covalent character in ionic bonds (Fajen’s Rule)

The topic of chemical bonding covers 5% marks in chemistry paper and these topics require a thorough understanding of the concepts.

Solid state does fall under the important topics, which help you in scoring for JEE. Following are the concepts that should be studied carefully:

Classification of solids, Crystalline state, Seven crystal systems (cell parameters a, b, c, ?, ?, ?), Close-packed structure of solids (cubic), Packing in fcc, bcc and hcp lattice, Nearest neighbours, ionic radii, simple ionic compounds, point defects.

Q.11: What are the important topics included in JEE Mathematics syllabus?

Here are the important topics from the Mathematics Syllabus:

  1. Coordinate Geometry
  2. Continuity/ Differentiability, Limits
  3. Complex Number
  4. Quadratic Equation
  5. Trigonometry
  6. Sequence and Series
  7. Integral Calculus
  • Calculus:

Calculus is undoubtedly the highest important topic for the JEE exam as this topic has the largest influence on modern-day mathematics. There are two branches for this domain viz. integral and differential calculus. The study of calculus could be termed as the study of change which is quite similar to geometry being the study of shapes and study of operations done by algebra. The main topics under calculus include:

Differential Calculus and Integral Calculus

  • Trigonometry:

The domain of Trigonometry is recognized by everyone as one of the core math topics and has its own significance in the JEE Maths section. The ratios and functions of trigonometry are used frequently in questions during the exam. Once students have a good grip on the basic concepts in this topic, they will be on the way to score really well in the exam.
