Is There Any Error in the JEE Advanced 2021 Official Answer Key?

A significant concern has been raised about the accuracy of the JEE Advanced 2021 official answer key. Specifically, two questions in the organic chemistry section are being questioned by test-takers. This article delves into these concerns and explores the possible errors in the answer key.

The NH2OH Excess Question

The first question in question is NH2OH (Hydroxylamine) excess. Many students and even some prominent educators on YouTube, such as MKA Sir, have been particularly critical of this portion of the exam. The key challenge with these questions lies in understanding the optimal use of hydroxylamine in reactions and the effects of its excess on the reaction outcomes. According to MKA Sir, the official answer key may be incorrect, suggesting that the reactions may not have been handled accurately in the provided solutions.

The Sunlight Addition Question

The second critical question under scrutiny is the sunlight addition reaction. This reaction, although a standard topic in organic chemistry, appears to have been controversial in the JEE Advanced 2021 context. The focus of this reaction is the complex interplay between photochemical reactions and the addition of different molecules under sunlight. The official answer key, according to some analyses, may not have accounted for certain reaction mechanisms that are crucial for correct response evaluation.

Why These Questions Raise Concerns

Both of these questions pose significant challenges that could affect students' scores. The organic chemistry section of JEE Advanced often tests a deep understanding of complex structures and reactions, requiring a nuanced approach. These specific questions, if answered incorrectly, can significantly impact a student's performance in the exam.

What to Expect Next?

As the doubts about these questions continue to surface, there is anticipation of further clarifications from the JEE advanced authority. This could involve re-evaluation of the answer keys, which may lead to changes in the final scores. It is crucial for students to remain informed and alert, as any changes in scores can have a lasting impact on their academic and career prospects.

Conclusion

The discussion around potential errors in the JEE Advanced 2021 official answer key highlights the importance of thorough examination and critical thinking in standardized tests. As the academic world awaits further developments on these questions, students and educators alike stand to gain valuable insights from such discussions.
