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.

All the Best!
ASSERTION : Isomorphous substances form crystals of same shape and can grow in saturated solution of each other. REASON : They have similar constitution and chemical formulae.
ASSERTION : Zinc is obtained from the roasted or calcined ore (ZnO) by heating with calculated quantity of coal or coke in a reverberatory furnace, when C reduces the metal oxide to free metal. REASON : The process of extracting the metal by reduction of its oxide ore with carbon is called smelting.
ASSERTION : Decreasing order of van der Walls’ radii is : Cl > N > O > H. REASON : van der Waals’ radii increase as the number of energy level increases and decrease as nuclear charge increases.
ASSERTION : Geometry of SF4 molecule can be termed as distorted tetrahedron, a folded square or see-saw. REASON : Four fluorine atoms surround or form bond with sulphur molecule.
ASSERTION : Sodium reacts with oxygen to form Na2O2 whereas potassium reacts with oxygen to form KO2. REASON : Potassium is more reactive than sodium.
ASSERTION : The maximum and minimum oxidation number of sulphur are – 2 and +6 respectively. REASON : SO2 behaves both as an oxidising as well as reducing agent. However, SO3 can only as an oxidising agent.
ASSERTION : There is a dip in the melting point of Mn in the first transition series. REASON : It has high enthalpy of atomization.
ASSERTION : A nearly tetrahedral arrangement of the orbitals about the oxygen atom allows each water molecule to form hydrogen bonds with as many as four neighbouring water molecules. REASON : In ice each water molecule form four hydrogen bonds as each molecule is fixed in the space.
ASSERTION : BF3 molecule has zero dipole moment. REASON : F is electronegative and B – F bonds are polar in nature.
