JEE Main 2024 Session 2: 5 Important Chemistry Topics for Students Who Missed JEE Session 1 |

[ad_1]

JEE Main 2024 Session 2: The National Testing Agency (NTA) recently released the Joint Entrance Examination 2024 January Session 1 results on its official website jeemain.nta.nic.in. Candidates can check their results by visiting the official website and logging in with their application number and date of birth. Once logged in, candidates can view and download their scorecard directly from the portal.
The JEE Main session 2 registration process began on February 2, 2024, after the JEE Main session 1 examination round concluded. Candidates who were unable to register for session 1 due to various reasons like exam date clash, lack of preparedness and others, will be able to register on the NTA JEE portal till March 2, 2024.
The second session of JEE Main 2024 provides an excellent opportunity to correct any errors from the first session. With the exams scheduled to be held in April, it becomes more manageable after preparing for the January session and completing board exams. The NTA earlier announced that the examination round for JEE Main session 2 is expected to commence on April 4, and will go on till April 15, 2024. Results will subsequently release on April 25, 2024.
The JEE Mains syllabus 2024 comprises three main subjects: Physics, Chemistry, and Mathematics. Each subject comprises a distinct array of topics evaluated in the examination. Among these, Chemistry is accepted as one of the more scoring yet challenging subject by aspirants.
Here are 5 important chemistry topics that JEE Main session 2 aspirants must not skip while preparing:
Colligative Properties
Understand concentration units, such as molality and molarity, as well as dilution methods. Understand colligative properties like vapour pressure reduction, boiling point elevation, freezing point depression, and osmotic pressure. Use these properties to solve problems with concentration, molecular weight, and phase equilibria.
Organic Chemistry
Learn about reaction mechanisms, functional groups, and reactivity patterns in organic chemistry. Concentrate on key concepts such as hydrocarbons, alcohols, phenols, aldehydes, ketones, carboxylic acids, and amines.
Understand stereochemistry concepts like chirality, optical isomerism, and conformational analysis. Practice different reaction mechanisms like nucleophilic additions, eliminations, substitutions, and rearrangements.
Chemical Equilibrium and Thermodynamics
Understand the principles of Le Chatelier’s principle and the reaction quotient (Qc), as well as how to perform calculations with equilibrium constants (Kc) and their relationship to Qc. Understand how enthalpy, entropy, and Gibbs free energy (ΔG) affect reaction spontaneity and feasibility. To gain a thorough understanding of chemical equilibrium and thermodynamics, use ΔG and its relationship to equilibrium constants to predict and assess reaction direction.
Complex Ion Formation, Ligands etc.
Understand how complex ions form with ligands bonding to a central metal ion, coordination numbers indicating ligand attachment, and oxidation states showing metal ion charge.
Learn about isomerism in coordination compounds, including geometrical (ligand spatial arrangement) and structural (ligand connectivity) types.
Know inner sphere (directly bonded ligands) and outer sphere (indirectly bonded ligands) complexes, and their properties. Practice naming, stability assessment, and reaction prediction in coordination compounds.
Chemical Bonding
Candidates should grasp the fundamentals of ionic, covalent, and metallic bonding, as well as master Lewis structures and VSEPR theory for shape and polarity prediction. They should also be proficient in hybridization concepts (sp, sp2, sp3) and their impact on molecule geometry and properties. Additionally, aspirants should delve into bond strength, bond energies, and the factors influencing them to gain a comprehensive understanding of chemical bonding.
