Question

• A. Both the statements are true.
• B. Statement-I is true, and Statement-II is false.
• C. Both the statements are false.
• D. Statement-II is true, and Statement-I is false.

Answer 1

Answer:

B. Statement-I is true, and Statement-II is false.

• Ionic compounds are brittle because of strong electrostatic forces of attraction between the ions.

• When pressure is applied, these ions get displaced and like charges come close resulting in repulsion and breaking of the crystal lattice.

• Hence, statement I is true.

• Ionic compounds have high melting and boiling points due to strong electrostatic forces.

• Hence, statement II is false.
