-
4.Which of the following correctly explains the difference between non-polar and polar covalent compounds, along with appropriate examples?
- A.Non-polar covalent compounds have equally shared electrons between identical atoms (e.g., H₂, CH₄), while polar covalent compounds have unequally shared electrons due to electronegativity differences (e.g., H₂O, HCl).
- B.Non-polar covalent compounds involve ionic bonds (e.g., NaCl), while polar covalent compounds involve metallic bonds (e.g., Cu).
- C.Non-polar covalent compounds have unequal electron sharing (e.g., O₂, N₂), while polar covalent compounds have equal electron sharing (e.g., CO₂).
- D.Non-polar covalent compounds occur only in gases (e.g., HCl), while polar covalent compounds occur only in liquids (e.g., H₂O).
-
5.Which of the following sets correctly lists the characteristic properties of electrovalent compounds?
- A.Gaseous at room temperature, low melting points, poor conductors of electricity, do not ionise in solution.
- B.Solid at room temperature, high melting and boiling points, conduct electricity in molten state or solution, ionise in solution.
- C.Liquid at room temperature, moderate melting points, conduct electricity only in solid state, do not ionise in solution.
- D.Solid at room temperature, low melting points, conduct electricity in solid state, ionise only in gaseous state.
