Here are some of the samples MCQ’s of chemistry with answers from Pakprep.com.
MCQ’s from Topic: Gases, Liquid & Solid
The graph between temperature in o C and volume of a gas shall cut the temperature axis at?
- Answer A : 0 0C
- Answer B : 273 0C
- Answer C : -273 0C
- Answer D : -546 0C
Reason: The straight line between V and T shall cut the temperature axis at -273 o C or O K. At this temperature the volume of gas would be zero.
MCQ’s from Topic: Basics of Chemistry
Empirical formula and molecular formula of a compound?
- Answer A : Are always same
- Answer B : Are always different
- Answer C : May be same or different
- Answer D : Same only for the inorganic compounds
Reason: Molecular formula = n (Empirical formula) where n may have value 1, 2, 3….. So if n = 1 then they both are equal else they are different.
MCQ’s from Topic: Atomic Structure
(n + l) value for 5f orbital will be?
- Answer A : 5
- Answer B : 6
- Answer C : 7
- Answer D : 8
Reason: As the n value is always the digit thus in this case the value of n = 5 while the value of azimuthal quantum number (l) is 3 thus for (n + l) the value will be 8.
