NEET 2023 exams are just around the corner and students are preparing for it with their own set of strategies. From the previous trends, it has been observed that Physics turns out to be the toughest section while Chemistry consumes lesser time and is often a scoring section provided all your facts are clear, along with conceptual clarity, and reactions being at your tips. How does a student gain mastery over these reactions?
Well, it has been discovered after a careful analysis on NEET topper over the years that such students are equipped with good strategies, one such for chemistry is the use of hand-made customized notes, with most important equations/reactions highlighted for them to remember even when woken up from slumber.
Trending: NEET 2023 exam
Out of these, the Chemistry section has something called name reactions, which students often stumble upon in the exams.
What are Name reactions?
These are chemical reactions titled after a person who is credited with either discovering the reaction or developing it.
Those candidates who are to appear for crucial engineering and medical entrance exams, these name reactions from Organic chemistry section are pivotal. It has been observed from past trends that these questions are recurring in nature in Board exams class 12, and even in competitive exams such as JEE Advanced, JEE Main, JIPMER and NEET.
Given the vastness of the NEET syllabus combined from class 11 & 12, smart learning methodologies are deemed as the most effective way out. As discussed, Chemistry is a scoring section, especially the Organic chemistry sub-section. With this article we aim at helping students in a small yet effective way by listing down the 5 most important name reactions one must know from the Organic chemistry section. The reactions that have been made to the list are picked after analysis from previous years’ question papers.
Do not try the “learn and vomit it out” technique with organic chemistry, it can act up horribly. It’s better to have transparency with concepts, for this NCERT books are the best. Get a fair idea of concepts, a better learning advice for organic chemistry, practise in such a way that NCERT is at your tips. With this, you will have an explicit comprehension of every single concept. In addition, you may also refer to the Interactive Organic chemistry book and Organic Chemistry by Morrison and Boyd. These books offer a plethora of information, outlined to enrich students with information having a good balance of theoretical knowledge on all Organic chemistry topics as well as a good amount of examples solved with practice exercises and flow charts.

Here comes the list of 5 most important Name reactions every NEET aspirant must know(ordered in random):
1. Etard reaction
When an aromatic hydrocarbon is treated with a mild oxidizing agent such as chromyl chloride CrO2Cl2 it produces aldehydes.
2. Aldol condensation
Condensation of two molecules of ketones or aldehydes having a-hydrogen in the presence of base [dil. NaOH, Na2CO3, Ba(OH)2]. It results in the formation of b-hydroxy ketone or b-hydroxy aldehyde respectively. Put together, it is known as aldol.
3. Cannizzaro reaction
This self-oxidation reduction reaction occurs when aldehydes lacking a-hydrogen atom experience a self-redox or a disproportionation reaction. All this in the presence of aqueous solution(50%) or ethanolic solution of alkali wherein one of the molecules is being reduced to alcohol and the other of which is undergoing oxidation to the salt of the corresponding acid.
4. Crossed aldol condensation
A reaction is referred to as a crossed aldol condensation when an aldol condensation of various molecules of ketones or aldehydes or one of ketone and one of aldehyde takes place. The end product of this reaction is a mixture of various products.
5. Clemmensen reduction
Aldehydes and ketones in this method are reduced with Zn-Hg amalgam and concentrated HCl.
These were some important reactions frequently appearing in competitive exams from Chemistry. Students must learn these name reactions from Organic chemistry to ace Chemistry section.
