Question

Which of the following statements are usually correct for carbon compounds?

(i) They are good conductors of electricity.

(ii) They are poor conductors of electricity.

(iii) They have strong forces of attraction between their molecules.

(iv) They do not have strong forces of attraction between their molecules.

• A. (i) and (iii)
• B. (ii) and (iii)
• C. (i) and (iv)
• D. (ii) and (iv)

Answer 1

The correct option is D (ii) and (iv)

Carbon compounds exhibit covalent bonding and thus do not form ions in aqueous solutions. Therefore, carbon compounds are poor conductors of electricity. Also carbon compounds are bonded by weak Van der Waal's forces of attraction due to the polarity of molecules.
