AIIMS (All India Institute of Medical Sciences) MBBS entrance exam for admission to the undergraduate medical course in AIIMS is to be held on 25th and 26th May 2019. For mere 807 seats, more than 3.5 lacs candidates gave exam in 2018. As the number suggests, AIIMS exam is more competitive than any other competitive exam. Every aspiring Medical Student dream to clear AIIMS entrance exam and wants to get his/her MBBS degree from this prestigious institute. To getting through the AIIMS entrance exam requires a thorough understanding of concepts as this exam tests the same through its variety of questions (MCQs & A&R) in Physics, Chemistry and Biology, and awareness about current affairs. From 2018, the AIIMS MBBS exam has started to be conducted on two days, over a total of four examination slots of three-and-a-half hour’s duration. The AIIMS examination will be a Computer Based Test (CBT), another difficulty added for many candidates who are not pretty comfortable to the CBT. To help you sail easily through the storm of AIIMS entrance exam, we are here running a quiz. Read on to know more.
AIIMS exam will consist of 200 objective type questions. This comprises of 60 questions (40 MCQ’s + 20 A&R questions) from each Physics, Chemistry and Biology along with 10 MCQs in Current Affairs and 10 MCQs in Logical Reasoning. Assertion & Reason section is a trickier one, as it is difficult to come up to the correct choice easily. Assertion and Reason are two statements which may or may not hold any relation to each other and can be correct or incorrect. It is taxing to understand whether the two statements are related and the reason gives the correct explanation of the assertion or not. Any wrong response consumes your hard-earned points from the MCQs part. But, a GOOD Practise of this section can save you from such dreadful situation.
To help you get habitual of the AIIMS exam’s demand and pressure, we are running a weekly quiz campaign on Assertion & Reason section. This will help you prepare well for the AIIMS exam. On this page, Assertion & Reason Quiz for Chemistry will go live once in a week. Take these quizzes which are especially designed to give you the best opportunity to strengthen your concepts to CRACK AIIMS Entrance Exam!
All the Best!

ASSERTION : The cell potential of mercury cell is 1.35 V which remains constant. REASON : In mercury cell, the electrolyte is a paste of HgO and ZnO.
ASSERTION : The transition of electrons n3 → n2 in H atom will emit greater energy than n4 → n3. REASON : n3 and n2 are closer to nucleus than n4.
ASSERTION : If more and more solute is added to a solvent, the freezing point of the solution keeps on becoming higher and higher. REASON : Presence of large amount of the solid solute does not allow the solution to freeze.
ASSERTION : van der Waals’ equation explains the behaviour of ideal gases. REASON : Ideal gases can only be compressed.
ASSERTION : In an electrochemical cell, concentration of the anodic half-cell increases while that of cathodic half-cell decreases when the two electrodes are joined by a wire. REASON : At anodic half-cell metal oxidises to metal ion dissolving the ion in the solution thus, its concentration increases at anode and decreases at cathode due to reduction of metal ions.
ASSERTION : Most probable velocity is the velocity possessed by maximum fraction of molecules at the same temperature. REASON : On collision, more and more molecules acquire higher speed at the same temperature.
ASSERTION : The molecules on the surface have lesser energy. REASON : During adsorption, the surface of solid is in a state of relaxation.
ASSERTION : Enthalpy of formation of O2 molecule at 298 K and 1 atm pressure is zero. REASON : Enthalpy of formation of all the elements at STP is zero.
ASSERTION : If the solubility of AgCl in water is 1.5 × 10–10, then its solubility in 0.01M NaCl aqueous solution is 1.5 × 10–8 M. REASON : NaCl dissociates completely so [Cl–] = 0.01 M.
ASSERTION : In caesium chloride crystals, Cs+ ions adopt bcc arrangement. REASON : For bcc arrangement, number of tetrahedral sites is double the number of atoms in the packing.
