Question

Organic conductors are known for their:

• A. High melting points
• B. Ability to conduct electricity through $\pi$-conjugated systems
• C. Magnetic properties
• D. Transparency in the visible light spectrum

Hint:

In organic conductors, look for $\pi$-bonds! Electrons flow through these delocalized paths — that’s the secret to their conductivity.

Answer 1

The Correct Option is B

Organic conductors are carbon-based materials that can conduct electricity — a surprising feature, since most organic compounds are insulators.
How Do They Conduct Electricity?

• Organic conductors contain long chains or planes of molecules with alternating single and double bonds, known as $\pi$-conjugated systems.
• In these systems, electrons are delocalized and can move along the chain, facilitating electrical conductivity.
• Examples include materials like polyaniline, polypyrrole, and polyacetylene — used in flexible electronics and sensors.

Why Other Options Are Incorrect:

• (A) High melting points: Organic compounds typically have lower melting points than inorganic metals or ceramics.
• (C) Magnetic properties: Organic conductors are not known for magnetic behavior.
• (D) Transparency in visible light: Not a defining property; many organic conductors are opaque.

Thus, the electrical conductivity in organic conductors is due to their $\pi$-electron delocalization in conjugated systems.
