Diamond does not conduct electricity, because - |
| A. | It's structure is very compact |
| B. | It is of crystalline nature |
| C. | There are only carbon atoms present in it |
| D. | No free electrons are present in it |
| Answer» D. No free electrons are present in it | |
|
Explanation: Diamond has a giant molecular structure. Each carbon atom is covalently bonded to four other car-bon atoms. There are no free electrons or ions in diamond; so it does not conduct electricity. Except for most blue diamonds, which are semiconductors, diamonds are good electrical insulators. |
