All of the following are correct regarding water except?
Correct Answer: C. It is non-polar in nature
One-liner
Water is polar in nature, not non-polar, due to the unequal sharing of electrons between oxygen and hydrogen atoms.
132.
Which of the following is not basic in nature?
Correct Answer: B. Aluminum oxide
One-liner
Aluminum oxide is not basic in nature; it is amphoteric, meaning it can react with both acids and bases.
133.

Past Paper MCQ
Which of the following is an electrolyte?
Correct Answer: D. NaCl
One-liner
NaCl (sodium chloride) is an electrolyte because it dissociates into Na⁺ and Cl⁻ ions in water, allowing the solution to conduct electricity.
135.
How many atoms of carbon are present in 18g of glucose C₆H₁₂O₆?
Correct Answer: A. 3.6 × 10²³
One-liner
18g of glucose (C₆H₁₂O₆) contains 3.6 × 10²³ atoms of carbon.
136.
Which of the following is a saturated hydrocarbon?
Correct Answer: B. CH₃-CH₂-CH₃
One-liner
CH₃-CH₂-CH₃ (Propane) is a saturated hydrocarbon because it contains only single bonds between carbon atoms.
137.

Correct Answer: D. 1.83 D
One-liner
The dipole moment of H₂O (water) is 1.83 D.
138.
Sulphuric acid is a _ acid.
Correct Answer: D. Oxoacid
One-liner
Sulphuric acid is an oxoacid because it contains oxygen, hydrogen, and a central non-metal atom (sulphur).
139.
Which of the following molecules has no net dipole moment?
Correct Answer: C. CCl₄
One-liner
CCl₄ (carbon tetrachloride) has no net dipole moment because its symmetrical tetrahedral geometry cancels all individual bond dipoles.
140.
Which of the following compounds would have the highest boiling point?
Correct Answer: C. CH3OH
One-liner
CH3OH (Methanol) has the highest boiling point among the given compounds due to the presence of hydrogen bonding.
