Read the given statements carefully and select the correct option. Statement-I: Most carbon compounds are poor conductors of electricity. Statement-II: Carbon compounds have low melting and boiling points as compared to ionic compounds.
Both the statements are false.
Statement-I is false but statement-II is true.
Statement-I is true but statement-II is false.
Both the statements are true.
Both the statements are true.
Carbon compounds are covalently bonded, leading to low intermolecular forces and lack of free charge carriers, confirming both statements.
Carbon compounds are covalently bonded, leading to low intermolecular forces and lack of free charge carriers, confirming both statements.
Analyze Statement-I
Most carbon compounds are formed by covalent bonds. Since they do not produce ions in solution and have no free electrons, they are poor conductors of electricity.
Analyze Statement-II
Because carbon compounds are held together by weak intermolecular forces rather than strong electrostatic forces (like in ionic compounds), they exhibit significantly lower melting and boiling points.
Conclusion
Since both scientific principles described in Statement-I and Statement-II are factually correct, Option D is the valid answer.
A: Both statements are verified as true facts. B: Statement-I is true, not false. C: Statement-II is true, not false.
D is correct because both Statement-I and Statement-II are scientifically accurate descriptions of the chemical properties of carbon compounds.
Always differentiate between ionic and covalent properties; ionic compounds are typically hard with high melting points and conduct electricity in molten/aqueous states, while covalent compounds are the opposite.
