Notably, by knowing the chapter-wise weightage for JEE Chemistry, the student can decide which topic needs to be focused on more. The questions asked in the examination paper are mostly direct and based on key concepts. Some calculation-based questions are also there. Students should follow the <\/span><a href=\"https:\/\/www.aakash.ac.in\/blog\/jee-main-revision-guidelines-and-best-practices-to-follow\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">JEE Main 2022 Revision Plan<\/span><\/a><span style=\"font-weight: 400;\"> to ace JEE Main.

These cover crucial topics like Thermodynamics, Atomic structure, S-Block Elements, Chemical Bonding, etc.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The JEE Main Chemistry section is divided into organic chemistry, inorganic chemistry, and physical chemistry. These sections carry a significant weightage, but organic chemistry is the most scored in all of these. There is almost a constant weightage of organic chemistry every year. Here, chapter-wise important questions are divided into physical, inorganic, &amp; organic chemistry.<\/span><br \/>\n<a href=\"https:\/\/www.aakash.ac.in\/jee-mains-answers-key-solutions?utm_source=blog&amp;utm_medium=website&amp;utm_campaign=jee_main_2022_answers_solutions\"><img decoding=\"async\" src=\"https:\/\/d20x1nptavktw0.cloudfront.net\/wordpress_media\/2022\/07\/1-4.jpeg\" width=\"100%\" \/><\/a><\/p>\n<h2>Chapter-wise Important Questions in JEE Main Chemistry<\/h2>\n<h3>Physical Chemistry<\/h3>\n<p><strong>Some Basic Concepts of Chemistry<\/strong><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A 0.2 g quantity of an organic compound gave 0.188 g of AgBr via the Carius method to estimate halogens.

Which of the sections in JEE Chemistry Syllabus has the highest weightage?<\/h3>\n\t\t\t\t\t<div class=\"\">\n\t\t\t\t\t\t<p>The organic chemistry portion is the most essential for the preparation of the chemistry section in the JEE Main Syllabus. Every topic in the organic chemistry portion is significant. The questions in organic chemistry are not very difficult. It just demands clarity of basic concepts.\u00a0<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<h3>2. Is studying from the NCERT textbook sufficient for JEE Main Chemistry Portion?<\/h3>\n\t\t\t\t\t<div class=\"\">\n\t\t\t\t\t\t<p>In the JEE Main Chemistry section, around 80% of questions in the examination paper are asked by the NCERT, either directly or indirectly. If students have read NCERT sincerely, they can competently solve 65-70% of the questions.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<h3>3. Can the inorganic chemistry portion be skipped in JEE 2022 preparation?<\/h3>\n\t\t\t\t\t<div class=\"\">\n\t\t\t\t\t\t<p>The students are advised not to skip the inorganic chemistry portion. It will help the students in scoring good marks, as there are no numerical questions asked in inorganic chemistry, unlike the physical chemistry portion. Students have to memorise things, and if they have a sound memory, then they can easily score high in inorganic chemistry.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<h3>4. How to master the chemistry section of JEE 2022?<\/h3>\n\t\t\t\t\t<div class=\"\">\n\t\t\t\t\t\t<p>Students should focus more on the organic chemistry portion. Complete the important &amp; easy to score chapters first. They should give enough time to important but tricky to understand chapters. Do daily revision. Students should go through things students need to know to succeed in JEE Main 2022.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\n","protected":false},"excerpt":{"rendered":"<p>The students preparing for the JEE Main 2022 must know that the Chemistry subject is highly significant.
