Question

The conductance of transition metal is not much affected when it forms interstitial carbide because:

• A. The carbide anion helps in conduction
• B. The carbon atoms occupy octahedral holes and so does not affect electrical conductivity
• C. The carbon atoms react with metal and liberate electrons
• D. The conduction is due to holes

Answer 1

The correct option is B The carbon atoms occupy octahedral holes and so does not affect electrical conductivity

The conductance of transition metal is not much affected when it forms interstitial carbide because The carbon atoms occupy octahedral holes and so does not affect electrical conductivity

Hence option B is correct.
