Sample Questions

Q1.A student finds that a soap solution appears cloudy/turbid. What is the scientific explanation for this observation?

  • ASoap micelles are large enough to scatter light (Tyndall effect), making the solution appear cloudy
  • BSoap is impure and contains solid particles
  • CSoap reacts with water to form a precipitate
  • DThe soap has not fully dissolved

Q2.How does soap remove oily dirt from cloth?

  • ASoap forms micelles that encapsulate oil droplets; ionic ends face water, hydrocarbon ends face oil
  • BSoap dissolves oil directly in water
  • CSoap neutralises the dirt chemically
  • DSoap increases the density of water

Q3.What is ethanol commonly called?

  • AMethanol
  • BAlcohol
  • CAcetic acid
  • DPropanol

Q4.What is catenation?

  • AThe ability of carbon to form bonds with other carbon atoms
  • BThe ability of carbon to burn in oxygen
  • CThe process of breaking carbon chains
  • DThe formation of ionic bonds by carbon

Q5.What is the name of C60, the carbon allotrope shaped like a football?

  • AGraphene
  • BBuckminsterfullerene
  • CCharcoal
  • DCarbon nanotube
