## Chemistry Aptitude Quiz

IIT JEE exam which consists of JEE Main and JEE Advanced is one of the most important entrance exams for engineering aspirants. The exam is held for candidates who are aspiring to pursue a career in the field of engineering and technical studies. Chemistry is important because everything you do is chemistry! Even your body is made of chemicals. Chemical reactions occur when you breathe, eat, or just sit there reading. All matter is made of chemicals, so the importance of chemistry is that it's the study of everything..

Q1. Select the correct statement
•  It causes nuclear reactions
•  It causes thermal burns
•  It alters the chemical structure of atom molecules
•  It causes electrons to be captured by the nucleus
Solution
Part C

Q2.Select the correct statement
•  MRI uses radiowaves to stimulate certain nuclei in the presence of magnetic field
•  P-32 is used for leukemia therapy
•  I-123 is used in imaging the brain
•  All of the above
Solution
Part D

Q3.  One atomic unit is equal to
•  1.492×10^(-3) ergs
•  1.492×10^(-2) ergs
•  1.492×10^(-10) ergs
•  None
Solution
Part A
Q4.   Of the following nuclides, the one most likely to be radioactive is
•   _15^31 P
•   _30^66 Zn
•   _7^14 N
•   _6^14 C
Solution

(d)
_6^14 C n=14-6=8
p=6
n/p=8/6=1.33>1
Hence, _6^14 Chas n/pratio greater than 1. It emits particles to have n/p=1.Thus, neutron changes to proton by emission of Î±-particles
_6^14 C→ _7^14 N+ _(-1)^0 e
Q5.Which is the best description of an alpha particle?
•  Charge +2; mass of 4 amu; high penetrating power
•  Charge +2;mass of 4 amu;low penetrating power
•  Charge -1; mass of 0 amu;medium penetrating power
•  Charge 0; mass of 0 amu,no penetrating power
Solution
(b)
( _2 He^4 )^(2+)
Î±- particles have low penetrating power. It is positively (+2) charged helium nucleus

Q6. The negative value of packing fraction indicates that the isotope is
•  Unstable
•  Very stable
• Artificial
•  Stable
Solution
Part D

Q7.The maximum number of electrons that can have principle quantum number, n=3 and spin quantum number, m_s=-1/2, is
•  3
•  5
•  7
•  9
Solution

Q8.To trace the flow of blood, radioisotope used is
•  Co-60
•  Na-24
•  P-32
•  I-123
Solution
Part B

Q9.The radiant energy from the sun is due to
•  Combustion
•  Nuclear fusion
•  Nuclear fission
•  Chemical reaction
Solution
(b)
_1^1 H+ _1^1 H→ _1^2 H
_1^2 H+ _1^1 H→ _2^3 He…

Q10. The nuclear process that takes place when a hydrogen bomb is exploded is of the same nature as the process
•  In the center of the earth
•  In the sun and stars
•  During a red dust storm
• During atom bomb fission
Solution
(b) In hydrogen bomb, nuclear fusion takes place
