37. Graphite cannot be use(1) as a lubricant(2) in making pencils(3) in making electrode(4) as a cutting tool |
|
Answer» The delocalised electrons are free to move through the structure, so graphitecan conduct electricity. ... The layers ingraphitecan slide over each other because the forces between them are weak. This makesgraphite slippery, so it is useful as a lubricant .Due to its lack of hardness in it it cannot be used as a cutting tool. Hence, option 4 is correct. |
