Just one day before announcing the results, IIT has admitted a mistake in the answer sheet put on its website.
IIT had marked AD as correct answer to the multiple choice question No 35 of paper II of Physical Chemistry. There were several complaints on this particular answer and finally after deliberating IIT has decided to give 4 marks to all those who have given ACD as their choice for answer. “Yes, we have given four marks to all those who have given ACD as the correct answer to that question,” said GB Reddy, Organising Chairperson of JEE 2012.
RN Singh, senior professor of Physical Chemistry, Department of Chemistry, BHU, had contended that the answer given for that question was not correct. IIT has for the first time put the answer sheets on its website. Many complaints of errors in answers and ambiguity in questions had poured after that.
