Wrong Questions in NEET 2017:
NEET 2017 was successfully conducted by CBSE on 7th May, 2017 in 104 cities across the country. With a rise of 41.42% in the number of candidates registering for the exam – going up from 8,02,594 in 2016 to 11,35,104 in 2017 – more than 2200 institutions, based on their credibility and infrastructural reputation were made centers for NEET 2017. This year, the paper was conducted in 10 languages rather than the standard 8 till last year. Like previous years, though, NEET 2017 also had some controversial questions, answers to which could not be pinpointed exactly by students. In this article, find out about the wrong questions in NEET 2017.
This year, the paper contained 5 controversial questions, one each in chemistry and physics and three in Biology. Let’s look at them one by one.
The physics section:
The physics section contained one of the wrong questions in NEET 2017, Q.26 in Set R. Here’s how it went:
“Radioactive material ‘A’ has decay constant ‘8x’ and material ‘B’ has decay constant ‘x’. Initially they have same number of nuclei. After what time, the ratio of number of nuclei of material ‘B’ to that ‘A’ will be 1/e?”
Here, there’s a minor mistake, however, marks could be claimed for that. The trouble seems to be that the ratio should be inverted, for the question to match any of the given answers. That is, the question should read:
“Radioactive material ‘A’ has decay constant ‘8x’ and material ‘B’ has decay constant ‘x’. Initially they have same number of nuclei. After what time, the ratio of number of nuclei of material ‘B’ to that ‘A’ will be e?”
If the original question is taken into consideration, it does not seem to have any correct option!
This was one of the wrong questions in NEET 2017, the other one belonging to the Chemistry section:
2. The Chemistry Section:
Chemistry is one subject where ambiguity is always expected. Hence, it came as no surprise whatsoever when a controversial question was reported in the chemistry section of NEET 2017. Q.87 in Set R read:
“Which of the following pairs of compounds is isoelectronic and isostructural ?
(2) IBr2 – ,XeF2
(3) IF3, XeF2
Here again, the trouble seems to be that there is no match to the question as it is.
The problem is this: isoelectronic species do not have same number of VALENCE electrons; they just have the same number of TOTAL electrons.
Hence, the question should be rephrased to read:
“Which of the following pairs of compounds is isostructural and has same number of valence electrons?”
If the existing question is taken into consideration, it is highly ambiguous, and does not seem to have a correct answer as far as the current options go.
3. The Biology Section:
This section had 3 questions which had more than one correct options each, according to experts. These were Q.13, Q.42 and Q.85 in set W of NEET 2017
Q.13 in set W went:
“The hepatic portal vein drains blood to liver from?”
Among the options both (2) Stomach and (4) Intestine are correct. This is because both these organs are part of the Gastrointestinal tract. This fact can be verified from the books like “Grays Anatomy” and “Snells Clinical Anatomy“.
Q.42 in set W said:
“The function of copper ions in copper releasing IUD’s is?”
Both options (1) They suppress sperm motility and fertilising capacity of Sperms and (3) They make uterus unsuitable for implantation are correct. This fact can be inferred from the books like, “Practice of fertility control” by SK Chaudhuri and “Shaw’s textbook of Gynaecology.”
Q.85 in set W asked:
“ln case of a couple where the male is having a very low sperm count, which technique will be suitable for fertilisation?”
Here according to experts both options (C) Artificial Insemination and (D) lntracytoplasmic sperm injection. There is also an error in definition, as ‘very low sperm count’ is an extremely qualitative phrase, and does not disclose the degree of Oligospermia.
These were the 5 wrong questions in NEET 2017. What the officials plan to do with this is unclear for now; however, you can do your bit by challenging the answer key. Here are the steps to challenge the wrong questions in NEET 2017:
- Log in to the Official Website with your Registration Number & Password.
- Click on the ‘Key Challenge’ tab and select the relevant answer booklet code.
- Select on the question you want to challenge and submit.
