JEE Main 2023 Hydrogen Revision Notes

Firstly, it is said that hydrogen is the lightest atom, with only one electron. Also, the loss of this electron results in an elementary particle, the proton. Furthermore, this is a unique characteristic property of hydrogen. Moreover, hydrogen contains three isotopes, which are called protium, deuterium, and tritium. Only the tritium is radioactive among these three isotopes. Besides, it resembles both halogens and alkali metals. Most notably, because of its unique properties, it has occupied a separate position in the periodic table. Also, it cannot be found in the atmosphere of the Earth in its free state.

The hydrogen is prepared from the dihydrogen from petrochemicals by the water-gas shift reaction on the industrial scale. Furthermore, the H-H bond of dissociation enthalpy of the dihydrogen is highest for a single bond between the two atoms of any element. Moreover, this property is used in a hydrogen torch, which is ideal for welding. In addition to this, the reducing reaction of dihydrogen leads to the formation of water, hydrogen halides, ammonia, methanol, and more compounds. On the other side, heavy water is the other important compound formed by the electrolytic enrichment of normal water.

Preparation Tips of JEE Main Chemistry

Let us look at some of the important preparation tips of JEE Main chemistry.

• NCERT Books: Following NCERT Chemistry books is not enough to answer all the questions asked in JEE Main Chemistry. You have to read the books of other writers as well for the holistic JEE Main preparation. But it’s being said that they are the most solid material for building the fundamental blocks of all the chapters included in the syllabus. 

• The student must particularly pay attention to the highlighted or important exercises represented in these NCERT books. It is because they are the key to knowing basic theories of chemistry and pave the way for the students to know concepts that they will come across in higher-level chemistry texts like Atkins. It is also recommended to get more details of these books, practising as many NCERT Chemistry Exemplar questions.

• As we all know, it is essential to understand the JEE Main Chemistry syllabus, including the important chapters, which will help the students in preparation for JEE Main accordingly. Furthermore, they can also download the Revision Notes of JEE Main Chemistry in PDF format at the end of the post.

Weightage of Hydrogen in JEE Main
