Sample questions
-
1.Covalent compounds generally exist as gases, liquids, or soft solids because of which property?
- A.Strong force of attraction between molecules
- B.Weak force of attraction between constituent particles
- C.High molecular weight
- D.Presence of ionic bonds
-
2.What is a dipole molecule?
- A.A molecule with equal sharing of electrons between atoms, resulting in no charge separation.
- B.A molecule that has both slight positive and slight negative charges due to unequal sharing of electrons in a polar covalent bond.
- C.A molecule formed by the complete transfer of electrons from one atom to another.
- D.A molecule with only nonpolar bonds, showing no charge separation.
-
3.The electronic configuration of nitrogen is 2,5. How many electrons in the outer shell of a nitrogen atom are **not** involved in the formation of a nitrogen molecule (N₂)?
- A.Zero
- B.One
- C.Two
- D.Three
-
4.In ... symbols the electrons present are represented with the help of dots.
- A.Empirical
- B.Lewis
- C.Skeletal
- D.Condensed
-
5.Assertion: Ionic compounds have high melting points. Reason: Ionic compounds consist of ions held together by strong electrostatic forces. (a) Assertion and reason both are correct statements and reason is the correct explanation of the assertion. (b) Assertion and reason both are correct statements, but reason is not the correct explanation of the assertion. (c) Assertion is false, but reason is true (d) Assertion is true, but reason is false.
- a.Assertion and reason both are correct statements and reason is the correct explanation of the assertion.
- b.Assertion and reason both are correct statements, but reason is not the correct explanation of the assertion.
- c.Assertion is false, but reason is true
- d.Assertion is true, but reason is false.
