Give reasons Diamond is used as an abrasive. |
|
Answer» SOLUTION :In diamond, carbon is `sp^3` hybridised. Each carbon atom is bonded to four other carbon atoms with the HELP of strong covalent bonds. These covalent bonds are present throughout the surface, giving it a very rigid 3-D STRUCTURE. It is very difficult to break this extended covalent bonding and for this reason, diamond is the hardest SUBSTANCE known. Thus, it is USED as an abrasive and for cutting tools. |
