Describe the structuure of diamond. |
|
Answer» Solution :(i) Diamond is very hard. (ii) The carbon atoms in diamond are `sp^(3)` hybridised and bonded to four neighbouring carbon atoms by `SIGMA` bonds with a C-C bond LENGTH of `1.54Å`. (iii) This results in a tetrahedral arrangement around each carbon atom the extends to the entire lattice. (iv) Since all four valance electrons of carbon are involved in bonding there is no free electrons for CONDUCTIVITY. (v) Being the hardest element, it used for sharpening hard tools, cutting GLASSES, making bores and rock drilling. |
