Chemistry MCQs
Practice Chemistry multiple-choice questions for MUET competitive exams. Each question includes the correct answer and a short explanation, and past-paper questions are marked so you can revise both repeated and fresh material in one place.
Proton
Neutron
Electron
Alpha particle
ExplanationThe mass of an electron is approximately 1/1836 of the mass of a proton or neutron, making it the lightest of the listed particles.
1
2
12
13
ExplanationpH is defined as -log[H+]. For 0.01 M HCl (a strong acid), [H+] = 0.01 = 10^-2. Therefore, -log(10^-2) = 2.
Oxygen
Fluorine
Chlorine
Nitrogen
ExplanationFluorine is the most electronegative element in the periodic table.
1 mole
2 moles
3 moles
0.5 moles
ExplanationMolar mass of H2O = (2*1) + 16 = 18 g/mol. Moles = 36g / 18g/mol = 2 moles.
Single covalent bond
Double covalent bond
Ionic bond
Coordinate covalent bond
ExplanationA double covalent bond involves the sharing of two pairs of valence electrons.
Linear
Bent
Tetrahedral
Trigonal planar
ExplanationWith 4 bonding pairs and no lone pairs on the central carbon, methane has a tetrahedral geometry.
Charles's Law
Boyle's Law
Avogadro's Law
Dalton's Law
ExplanationBoyle's Law defines the inverse relationship between pressure and volume at constant temperature.
-COOH
-OH
-CHO
-NH2
ExplanationThe hydroxyl group (-OH) is the characteristic functional group of alcohols.
+3
+4
+6
+7
Explanation2(+1) + 2(Cr) + 7(-2) = 0 => 2 + 2Cr - 14 = 0 => 2Cr = 12 => Cr = +6.
Oxygen
Carbon Dioxide
Nitrogen
Argon
ExplanationNitrogen makes up approximately 78% of Earth's atmosphere.
