Most Important Formulas for JEE Chemistry

\mathrm{c= \frac{distance}{time}= \frac{Wavelength}{Time \:Period}=\frac{\lambda}{T}}

\mathrm{\because\nu = \frac{1}{T}}

\mathrm{\therefore c = \nu \times \lambda}

(i) Work done in reversible isothermal process

\begin{array}{l}{\mathrm{W}=-2.303 \mathrm{nRT} \log _{10} \frac{\mathrm{V}_{2}}{\mathrm{V}_{1}}} \\ {\mathrm{W}=-2.303 \mathrm{nRT} \log _{10} \frac{\mathrm{P}_{1}}{\mathrm{P}_{2}}}\end{array}

(ii) Work done in irreversible isothermal process

\\ \mathrm{ Work =- P_{ext. } ( V _2-V _1 )} \\ \mathrm{That \ is, \ Work =- P \times \Delta V }

At T = 298 K, Nernst equation is given as follows:

\mathrm{E_{cell}\: =\: E^{o}_{cell}\: -\: \frac{0.059}{n}log_{10}Q}

\text {Mass by Volume } \% \text { of a component }=\frac{\text { Mass of the component }}{\text { Total volume of solution }} \times 100

Questions related to JEE Main

Have a question related to JEE Main ?

We all know the importance of class 10th and class 12th marksheet. Class 10th is considered  like an birth certificate. These certificates play a big role in higher studies and in jobs . During, documents verification, class 12th marksheet is also seen,along with other proofs ,so it might create problems for you as your name would be different  in those documents. But don't worry.

If there is a mistake in name's spelling or father or mother name,then CBSE provide correction option to the students. For  correction in name in 12th marksheet, you can follow few steps.

Students can take the application form for name correction from the official website of CBSE board.

Fill the application form with correct details.

Submit the required documents like school leaving certificate .

Then you need to deposit some few for correction.

After completing the process, board will make the necessary corrections once the verification of original records of the school is done.




Hello,

Here’s a step-by-step guide to help resolve this issue:

  1. Contact School Authorities : Reach out to your school immediately. Explain the discrepancy in your name between your Aadhaar card and board registration. Schools usually have a process to handle name corrections.

  2. Submit Correction Application : Schools may ask for a written application, so provide one along with proof of your correct name (e.g., Aadhaar card). Request that they initiate the correction in your board records.

  3. Check with Board Office : If needed, contact your state or central board’s regional office directly to understand the procedure and required documents for name corrections.

  4. Update JEE Application : Once the name is corrected in the board records, you may need to update your JEE registration. Check with the National Testing Agency (NTA) helpline on how to proceed.

  5. Stay Calm and Follow Up : Keeping calm and staying proactive with regular follow-ups is essential. This is a common issue, and boards have processes to handle it.

Hope it helps !


Hello,

In case you have no surname mentioned on your Class 10th marksheet but every other document has it, make sure the name is correctly uniform everywhere and also while appearing for exams like JEE Mains. Here is how you can do:

  • Wait for the Response from CBSE: Since you have already requested your school to send a mail to CBSE for correction, wait for their response. CBSE may update your marksheet by including your surname, which will match with your other documents.
  • In case the corrected marksheet does not reach you before the closing date of the JEE Main 2025 application form then you can submit your application using your name since it will be there on your 10th marksheet. You can correct the details of your application form if there's a need for it within the correction window.
  • Carry photocopies of all documents that bear your surname, including caste certificate, state ID, etc. For verification, it might come in handy.
  • Affidavit of Name Consistency: This affidavit can be made where it will be established that both the names carrying the surname and not carrying the surname refer to the same individual. It may be produced at the time of admission for verification purposes, if required.
  • Follow up: Keep follow-up with your school and CBSE at regular intervals to speed up the correction process.

This will see you well through to JEE Mains and any further admission processes.

Yes, you will be eligible for JEE Main and JEE Advanced in 2025 and 2026.


JEE Main allows candidates to attempt the exam in three consecutive years following their Class 12th examination. Since you are reappearing for the Class 12th board in 2024-25 due to medical reasons, your eligibility will start from 2025. This means you can take JEE Main in 2025, 2026, and 2027.


For JEE Advanced, candidates can appear in the exam twice in consecutive years, beginning the year they complete their Class 12th. Since your Class 12th completion year will be 2025, you can take JEE Advanced in 2025 and 2026.


Your gap year, caused by health challenges, does not affect your eligibility. The examination authorities recognize that candidates might face unforeseen circumstances and determine eligibility based on the year of completion of Class 12th, not initial enrollment. Just ensure you meet the other basic requirements, such as minimum marks in the required subjects, when applying.


Focus on your preparation and health, and when you're ready, you’ll have the opportunity to pursue JEE with full eligibility.

Hello,

If a candidate uses a certificate issued through EWS on false grounds for entrance into JEE Mains or college admissions, things can go quite serious at the time of discovery. Here's what might follow:

Cancellation of Admission: If the false certificate issued is detected in the course of verification or later when the course has started running, the candidate's admission may be cancelled immediately.

Legal Action: In this activity, he shall be fraud when he use a false certificate. His punishment will be done via fines or further action against him, as per state-institutional rules on committing such an offense.

Candidate may get disqualified for such competitive exams in the near future because of this action that directly affects the field of education and career.

This leaves the candidate with a great loss in reputation, where they may not be in a position to continue with their studies or seek employment.

Use valid and genuine documents to avoid these risks.
